Confirmed: Pin P0.06 works as Uarte TX on the nRF52 DK.
-
@NeverDie yes, you're right
sorry i misread it 
Have fun!
-
As final confirmation I did re-program the Ebyte module as an nRF52 DK, then connected its P0.06 to the FTDI RX, and, voilà , it worked as expected. @scalz Thanks for the idea!
One small caveat: On the Ebyte module, P0.06 doesn't appear on the silkscreen (there's a typo where it's shown as P0.07 instead, resulting in there being two P0.07's on the silkscreen), so just pick the most obvious pin based on the numerical progression (or else consult the datasheet), and it will work.
-
In lieu of my breakout board, which hasn't yet arrived, I've been attaching wires directly to the module so that I can do more than just sit and wait for the BoB delivery. I'm now doing it this way:
and although crude it's working much better than just soldering the wire to the module with no mechanical support. Doing it the way pictured, the connections stay connected and don't break loose. Ironically, by the time my breakout boards finally do arrive, I may have already learned everything I needed them for.I am curious: how are the rest of you handling this issue?
[Edit: One other alternative: once my 1.27mm pitch generic protoboards arrive, I expect they'll offer up cleaner connection possibilities. At the moment, I'm also waiting for them to arrive from Aliexpress....]

Your idea of having the pin mapping be selectable within the sketch sounds great! A+. I'm really looking forward to that and hope that you can do it soon.

Not many solutions, I soldered wires directly to the modules too, I used thin&cheap wires from aliexpress. They are very convenient for this, easy to solder and very soft so not having any constraint on the solder joints when you manipulate them. Then I put module on the side of board with double sided tape and soldered other ends of the wires to a connector.
Then I flip everything and only look at the beautiful side of things

Thanks! By being "merged," does that mean it is now in the regular MySensors development release, and so I should reload a fresh copy of the MySensors development library?
Also, is this the way I should enable P0.21 as nReset (to enable hardware resets on P0.21), or should I instead be writing 0xFFFF directly to both the PSELRESET[0] and PSELRESET[1] registers to enable that?

The Board definition is independed from MySensors core living at https://github.com/mysensors/ArduinoBoards You have to follow the instructions, then you can install the MySensors nRF5 Boards via Arduino Board Manager.
Also, is this the way I should enable P0.21 as nReset (to enable hardware resets on P0.21), or should I instead be writing 0xFFFF directly to both the PSELRESET[0] and PSELRESET[1] registers to enable that?
Look into the Tools menu. For nRF52 MCU is a "Reset" menu. Switch it to "Enable"
-
@d00616
I got the pin mapping to work, but setting reset enable through the tool menu seems to have no effect. I subsequently drive P0.21 low (all the way to GND even), but no reset happens. Am I doing it wrong? Anyone gotten it to work?
-
@NeverDie
I also tried adding a 10K pullup resistor, and no change.At the moment I'm unfamiliar with the nRF52 API. What would the code be to set both those reset registers to 0xFFFF? That by itself should enable the reset on P0.21. I could try inserting it into the demo script and see if reset then works.
-
I guess it wouldn't be that simple, because I just now read that it requires a system reset after writing to those registers: https://devzone.nordicsemi.com/question/157603/can-i-enable-and-disable-nrf52832-reset-pin-when-code-is-running/ for it to take effect.

I tried to use the JLink tools to make the mass erase but it didn't want to connect to the module.
But then I have replaced the driver with Zadig and configured Arduino for NRF5 and it uploaded the LightSensor sketch, I can see it in the log of the controller. No mass erase needed, nor any unlock or related command.
Just plug and program for meI have some strange error messages but I guess they come from (very) dated firmware on my Segger clone

@Nca78 said in nRF5 Bluetooth action!:

I used the j-link Segger clone to do the mass erase, and then I switched to the DK to do the programming. However, today I was able to do the programming from the Segger clone on the Windows 10 computer, and the setup is less arduous than for programming an external chip using the DK (because with the Segger I didn't have to power the target chip independently during the programming).
-
So, I guess the way the code would read is:
- First check if the reset registers are already properly set.
- If so, then just move on to whatever is next.
If not, then properly set the reset registers and invoke the system reset.
Apparently a system reset doesn't change the values in the reset registers.
Of course, none of this would be needed if the reset enable from the tools menu worked, so I'd still prefer to do it that way if at all possible.
As I indicated earlier, the pin mapping on Rx and Tx did work using @d00616 new technique, so hurray for that. That much was an important victory in itself that's worth celebrating.
-
First nrf51822 module arrived already.
It's really small, here between an nrf24 SMD and the cdebyte 52832.
Soldering quality looks better than the pictures on AliExpress.

@NeverDie said in nRF5 Bluetooth action!:

The "Reset" menu was from my first approach creating user manageable boards for arduino-nrf5. I haven' tested it. With the reset menu I set the "-DCONFIG_GPIO_AS_PINRESET" option. This option should be processed in "cores/nRF5/SDK/components/toolchain/system_nrf52.c". If not the SystemInit() function is not processed in the startup code. This is a problem handling the chip errata. I have not time to check this at the moment.
Here is a PR which want to enable reset as default: https://github.com/sandeepmistry/arduino-nRF5/pull/91
-
Maybe the reset pin problem is hardware related? I say that because if I program the Ebyte module as a Nordic nRF52832 DK board, it still has the same issue. In contrast, the reset button on the actual nRF52832 DK board does work as expected.
-
I've confirmed that connecting P0.21 to GND and then removing it again on the Nordic nRF52832 DK does act as a reset. So, at the moment I have no idea why doing so on the Ebyte nRF52832 that's been programmed to think it's an Nordic nRF52832 DK doesn't do the same. There must be some hardware difference, right?
-
I've confirmed that on both the Ebyte Module and on the Nordic nRF52832 DK, there is continuity between the P0.21 pin on the chip and the P0.21 pin on the board pinout. So, there must be some other factor that accounts for the difference.
-
Making no headway on the reset topic, so for now I'm going to punt and move on to other things.
-
Success! I received some of these modules:

which I immediately programmed using the nRF52832 DK. This time, there was no need to first mass erase. Furthermore, this time P0.21 does indeed reset the module after it is pulled to ground and then released.So, from this I conclude there must be something peculiar to the Ebyte modules which prevents their resetting using P0.21.
It's nice to have different modules to compare amongst.

@NeverDie gotta catch them all

Anyone have a good sketch for measuring the battery supplied voltage on an nRF52? Some of the concepts from the old atmega328p may apply, but the specifics are going to be different, I'm sure.
-
Check on adafruits feather reference they use two resistors as a voltage divider for that simple and effective.

@NeverDie https://learn.adafruit.com/assets/39913
Top right corner of the schematic.

@NeverDie but a much better but more expensive solution would be a lipo fuel guage from spark fun they use a Max chip for that.
-
If supplied with less than 3.6V you can do it with ADC, 1.2V voltage reference and 1/3 prescaling.
But I've only looked at the theory yet.Rules are Vdd+0.3V max at the pin, and max 2.4V as input of ADC (after prescaling)
-
Well, as you all know, on the atmega328p you can read the 1.1v gap voltage using the battery voltage as the reference voltage, by doing analogRead(A0), and from just that one measurement then calculate the battery voltage by doing a little bit of math. So, I'm just wondering what the code is to do the equivalent of that (using 1.2v instead of 1.1v) on the nRF52832.

good choice

I tried this function call on an nRF52 DK, and it seems to work. I then tried it on an Ebyte module, treated as an nRF52 DK "board", and it reported zero voltage. So, probably I just need to do a pin mapping so that it reads the voltage on the proper pin. But which pin/mapping would it be? I thought that Vcc wouldn't really be mappable to anything but Vcc. I guess whichever analog pin (if that's what it is?) is connected to Vcc on the nRF52 DK is the pin I need to find and re-map to its equivalent pin on the Ebyte module. Hmmm.... I'll have to look into which one that would be.
-
Actually, something different may be going on. Here's the function definition:

Well, to debug that, I added the Serial.println(...) statements into the library code (see above) in an attempt to see which of the if-else branches is being taken, but none of the Serial.println(...)'s were printed!

-
Bracketing that and setting it aside, I do now notice this line in the BatteryPoweredSensor demo sketch:
int BATTERY_SENSE_PIN = A0; // select the input pin for the battery sense pointSo, if I map that A0 in the sketch to the A0 of the Ebyte Module, then maybe (hopefully) the voltage measurement will work on the Ebyte Module. I'll give it a try.
-
Unfortunately, after I add:
#include <mySensors.h>the locus of control goes somewhere else (I guess the gateway or something?). Anyhow, it makes this very hard to debug.
For instance, the pin of interest is PIN_AIN0. I can't find where it's defined, and I can't print out its value either, because of this locus of control issue.
Anyhow, I think I may wait for others to get up and running with their modules, and start facing the same issues. Maybe then we can help each other figure this stuff out.
-
@NeverDie I don't know why the println() doesn't work. There is an "DEBUG_OUTPUT(x, ##VA_ARGS)" macro, you can use when debug is enabled.
NRF_ADC is the nRF51 ADC and NRF_SAADC is the ADC of the nRF52. They are defined when "nrf.h" is included.

I just now did a brute force hack of the MySensors BatteryPoweredSensor sketch, where I copied and renamed the hwCPUVoltage function from the library and then called it from within a tight loop so that I never lose the locus of control. It worked!

Besides that it can now do println()'s, the other good news is that it looks like I won't need to change the pin assignment.
Too bad the demo sketch only transmits one byte of voltage information, rather than two bytes.

@NeverDie said in nRF5 Bluetooth action!:
I tried this function call on an nRF52 DK, and it seems to work. I then tried it on an Ebyte module, treated as an nRF52 DK "board", and it reported zero voltage.
I have tried the hwCPUVoltage() function with an Ebyte and an RedBear module. Both modules are reporting the voltage.

Received a new module. Here's a size comparison with the Ebyte Module:

@NeverDie Dam you why would you make it so wide? can it fit on a single bread board?
Also how did you get those so fast?
-
@Mike_Lemo said in nRF5 Bluetooth action!:
Dam you why would you make it so wide?
In 20/20 hindsight, you're right. At the time I designed it I had huge concerns that the range on the nRF52832 might be awful, because the Adafruit nRF52832 feather that I tested had poor range. So, I gave it a very large ground plane to see if maybe that cured the problem. Only later did I receive the Ebyte module, which turned out to have good range even by itself.
can it fit on a single bread board?
Sorry, you'll need two.
Also how did you get those so fast?
OSH PARK averages around two weeks for me. That's the main reason why I buy from them.

@Nca78
Thanks! Good to know.

Just realized it has 2 extra I/O on the side, and the SWD are only pads on top, which makes 8 I/O available, it's much more interesting than the NRF51822 version.

@Nca78
Is there even a way to program the nRF51822 version? I'd have to check, but I don't recall the two SWD pins being on its pinout.

That's good news. There must be something wrong with how I'm doing it. Which board type are you using for the Ebyte module?
-
From what I understand the NRF52832 has some kind of enforcer that allows different serial hardwares to be assigned to different pins
Now using the arduino IDE I want to use the I2C pins that are assigned hardwarely to different pins here is the situation
I have one PCB that has SCL connected to pin 20 and SDA to 21
and another PCB that has SCL connected to pin 11 and SDA to pin 12
I want to define the enforcer for the pins within their dedicated sketches without running around to the internal arduino files and change the pin assignment for each upload to each board.
How'd I do that? I assume you'd have to do some thing like that in the upper side of the personal code.
#define SDL...(Something else I don't know ) 11
#define SDA...(Something else I don't know ) 12

I think I have a better hypothesis as to what's going on in my situation: the ebyte module is getting hung-up trying to establish communication with the serial gateway. Looking at the output of the serial gateway, it looks as though it is receiving packets from the Ebyte module. However, looking at the Ebyte output, it thinks it is failing. So, the Ebyte never quite gets out of the "establish communication link" mode.
This doesn't occur, though, if I use an nRF52 DK, instead of an Ebyte module.
So, what might explain this is maybe the MISO pin on the Ebyte module isn't mapped right.
@d00616 Would you please share the pin mappings and board type that you are using for your ebyte module? Since you are having success, I think that will fix the problem.

Most components, like UART, SPI, Wire Bus, of the nRF5 series chips don't have a fixed pin mapping.

Well apperantly this function uses a PWM pin at 50% duty but the frequency varies according to the functiong user parameter now I just know how to active a PWM pin at 50% duty but not how to acces the NRF52 registers to change the frequency of the PWM.
I don't realy know how to access the registers you see at the product's PDF and the other process.

Does the nRF52 mcu communicate with its radio using SPI, or some other bus? Or are all the radio registers simply memory mapped?

Well, if the mcu uses SPI to communicate with the radio, then I simply need to define which SPI "pins" those are. Attached is the pin mapping file that I used to successfully map the pins for Rx and Tx.

@NeverDie if I'm not wrong you managed to connect the Ebyte module to your MySensors network, no ?
I did it anyway and it received data.
Radio is internally connected inside the nrf52 chip so I don't see how a module could have a different mapping ?
-
@Nca78 said in nRF5 Bluetooth action!:

Yeah, that's what I thought originally, and it probably is true. I'm just grasping at straws to understand why the "board" type seems to be affecting the radio communications. I'm also completely new to the mysensors way of handling radio, so that's getting in my way. I'm might have to try something more barebones before I can make sense of this.

I've confirmed it now. Even if I comment out all apparent radio message sends, the mere act of including:
#include <MySensors.h>results in a loss of control by the sketch itself to something within MySensors that wants to establish communication between the node and the gateway. Not even sure how that is happening. In any case, it is just overcomplicating the debugging, and I really don't want that right now because it is effectively hanging what I'm trying to do.
For now, all I want is a simple send packet--like either the mirf or the twh20 libraries have for the nRF24L01--with no complicating factors. Is that too much to ask? I can probably find that somewhere within the library, but how do I turn-off this loop that it's in where it's repetitively trying to establish the initial communication with the serial gateway?

@NeverDie said in nRF5 Bluetooth action!:

The module is connected to SWDIO/CLK, VCC and the GND near the radio. I don't remember which pin I used for Serial TX.
@NeverDie said in nRF5 Bluetooth action!:

The registers are memory mapped, the data transferred with "EasyDMA" into the memory.

The SecurityPersonalizer defines '#define MY_CORE_ONLY' before including 'MySensors.h'. In theory, you can use the radio functions defined in 'hal/transport/MyTransportHAL.h' directly. I had no luck with this, but I haven't invested time to debug this.

The registers are documented in the Infocenter and the bitfields.
I don't realy know how to access the registers you see at the product's PDF and the other process.
To access the registers, you have to add '#include <nrf.h>' to your code. Mostly the hardware is accesses by NRF_HWNAME->REGISTER
Doing PWM is a little bit complex. The code is different for nRF51 and nRF52. Look into wiring_analog_nRF51.c and (wiring_analog_nRF51.c)[https://github.com/sandeepmistry/arduino-nRF5/blob/c98a190eb34c0247eb8e0764a6367c7f9e51d2fc/cores/nRF5/wiring_analog_nRF52.c#L214]
If you clone this code, for nRF52 you have to use another timer, like TIMER2, because you can't define the interrupt routine twice.

Thank you it works !
That's probably when trying to use this function that I managed to unlock&erase the EByte module "by mistake"The only problem now is the range seems to be very bad
Less than 10m with just a brick wall and it fails to completely send the presentation messages.
EBytes nrf52832 module works well in the same conditions, same for their nrf24 modules.[Edit] in fact not that bad, it works ok when changing the orientation of the module. Could be due to the funky wiring but my bet is it on the tiny antenna design. My gateway is an old through hole nrf24 clone so range should not be a problem in an appartment with a PA/LNA gateway.

@d00616 said in nRF5 Bluetooth action!:

I'm happy to report this also worked when, just now, I programmed a new Ebyte module. Like d00616 said earlier, it's a much faster way to do a mass erase.
Unfortunately, and in contrast with the nRF52 DK, the new Ebyte module I just programmed is behaving the same as the Ebyte I've been experimenting with. No change.

Follow the instructions for ArduinoBoards and ArduinoHwNRF5
Do you know where can the arduino library folder be found with all the arduino functions?
The arduino-nrf5 port only implements functionality documented in the official Arduino Reference but mostly not more functionality available for SAMD :-(. Additional functionality like BLE or using included hardware must come from external libraries like MySensors.
A good way to implement the tone commands is to fork the arduino-nRF5 repository at github. Change what you need and create an pull request with reference to the Arduino reference. If you inform me about your PR I comment it to increase the chance for acceptance otherwise it's time to maintain an separate fork of this repository.

@NeverDie When choosing "MyNRF5Board nrf52832"?

-
At some point, I had to re-arrange the libraries though (don't remember which files or which ones) to get all this stuff working. Before that, it wasn't finding the files. Actually, I think this would be a good topic for discussion, to make sure we're all doing it the same way. If we're doing it differently, it might make cross-checking each others attempts more difficult. Also, maybe there's a better way than the brute-force way that I did it.
If anyone has interest, I can post how my libraries are currently structured. If nothing else, it would be a starting point for discussion on what to do (or not to do).

At some point, I had to re-arrange the libraries though (don't remember which files or which ones) to get all this stuff working. Before that, it wasn't finding the files. Actually, I think this would be a good topic for discussion, to make sure we're all doing it the same way. If we're doing it differently, it might make cross-checking each others attempts more difficult. Also, maybe there's a better way than the brute-force way that I did it.
If anyone has interest, I can post how my libraries are currently structured. If nothing else, it would be a starting point for discussion on what to do (or not to do).
Dunno that whole arduino BRF52832 programming thing seems too complicated just started to learn how to use the nordic SDK with eclipse until a proper solution is found.

It hasn't been easy, I'll grant you that. I get the impression d00616 probably does most of his work in Linux, and so some of the disconnect with the Windows IDE probably stems from that. Once we get the basics ironed out, though, I expect things will go more smoothly. In fact, I think we're almost there. A lot of the work for sleeping, measuring source voltage, etc., has already been done, which is far better than starting from scratch. And there's even example code, which helps tremendously.

Good news! Interestingly enough, the MockMySensors sketch seems to work fine when I load it onto the Ebyte. What a relief! So, I may try hijacking that sketch to convey voltage measurements instead of the BatteryPoweredSensor sketch that mysteriously hasn't been working on my Ebyte modules.

The Nordic SDK is more complete than Arduino-nrf5 at the moment, but there is no compatibility with MySensors.
The good news, with SDK 13 the 'Nordic Semiconductor ASA' License was changed. The old ASA was the reason for me to rewrite the complete ESB protocol. Now the license is much less restrictive. I think now the way is open to integrate SDK code into arduino-nrf5 or provide SDK based arduino-libraries.

I can't change the way of Windows driver handling, but when there are Windows specific issues then they bust be fixed.
