Hello,

Some news !
i buy a Jlink, and success in erase my nrf52832 with nrf prog, using method of berkseo.

Next i try to upload a basic sketch (blink) :

#define MY_RADIO_NRF5_ESB
#include <nrf.h>
#include <MySensors.h>

void setup() {
Serial.begin(9600);
hwPinMode(LED_BUILTIN,OUTPUT_H0H1);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

I have this :

I think its good, but when i put a led with a resistance on P0.08, nothing

could you help me more ?

LED_BUILTIN corresponds to po17

I thought I mastered nrf5 platform bit it looks I am not.
I have a PCB where i2c sensor is hardwired to po30 and po31 of nrf52832.
What changes I have to make in MyBoardNRF5.cpp?
Shall I bring lines 28/29 that have "A4" and "A5" in their desciption to 30th and 31st position in the list?

@ileneken3 have you returned the jumpers back?

@omemanti said in [nRF5 action!]Maybe that's the €3 solution for unlocking.

BMP is enough to unlock. BluePill costs ca. €2 and it's easily convertable to BMP

@mr_red said in nRF5 action!:

Is there any way to do this over the programmer?

Not in Arduino. In KEIL you can use RTT (pretty cool stuff, debug via SWD)
But if you just want to decrease a number of programmers, you can use Black Magic Probe, made from BluePill ($2 at Ali). It is 2-in-1 SWD and USB-UART converter on one PCB

Can you pls. upload the design files?

@rozpruwacz said in my first nrf5 ... NRF51/NRF52 which is better for MySensors ?:

So smd modules are no good for me

If so, your only choice is nrf52DK. Solid investment given you get jlink programmer with it

how do you guys solder nrf52840 modules without reflow oven?
they have many pads at the bottom

@hugob said in my first nrf5 ... NRF51/NRF52 which is better for MySensors ?:

• The programmer on the Arduino IDE is not working for me ("No J-Link" error, while there is a J-Link interface available), so I export a HEX fle form Arduino IDE and program the board with the nRFConnect tool from Nordic.

if read sandeep's notes on Githun, you'll find you have to replace the driver with Zaddig but then Jlink will stop functioning in Keil.
That's why I use BMP for Arduino-style programming as it has its own drivers and do not ruin jlink installation

@rozpruwacz I would strongly encourage you do start with nrf52832 ebyte mosule coupled with Nevrdie's breakout board. It is a) proven b) cheap c) breadboard friendly

@omemanti that's strange, I use the methos regularly and it worls fine.
Oh! Actually, sandeep's installation messes up Jlink drivers so they require reinstall for the method to work.
That's why I am using arduino nrf5 with BMP to completely separate Arduino from Jlink

@omemanti actually, all you need is to issue the following command:
nrfjprog.exe --recover

@speechsupply this thread is golden. I was so empowered that was able to easily switch to nRF SDK and to start producing (semi) commercial BLE-ANT device

@neverdie I am afraid it still relies on Softdevice

@neverdie what are potential advantages of micropython?

@neverdie I've setup the bootloader for my BT project and I confirm its much easier than it looks.
Can it be used for MySensors? For BT, I create a hex file in Keil and then upload it via nrftoolbox app.
Can the same procedure be used with MySensors? OTA needs Softdevice and Softdevice is not compatible with MySensors

Guys, remind me pls: is CR2450 enough for the nrf52 Ebyte module acting as a Mysensors node?
Is it capable to handle tx current spikes?
Energizer datasheet states 9ma as max curent pulse. Is it sufficient?

@nca78 said in SMD Reflow Oven / PID:

small 10*10cm hotplate

interesting. Do you use an ordinary kitchen hotplate?

@neverdie c'mon, you don't need any special syringe. Ordinary BD will do
Regarding the motor operated one, I actually printed out a full set of 3d parts for the motor oerated syringe but never assembled as there is no need.
If I ever decide to automate the process, I'll make an air driven station with 2 valves. Mechanic solder syringes are supposed to be used with this type of dispensers.

@neverdie yes, although I use the one in small cans and reload small amount into 1 ml syringe (with proper gauge needle!)

@neverdie
two hypothesis:
a) old paste
b) wrong needle gauge

I use Mechanic XG paste, works perfect

@neverdie said in nRF5 action!:

I didn't have good enough technique dispensing manually directly from a solder paste syringe,

what did you have issues with?

@mars-warrior said in nRF5 action!:

In the mean time I learned how a PID controller

Thanks!
I have to admit I've acquired pretty decent understanding of PID while working on my sous-vide machine

@mars-warrior said in nRF5 action!:

OSPId reflow controller

where did you get it?

Very nice indeed. I thought ground plains improve the range

@scalz actually, it might be ideal as a REPEATER given the form-factor. You just insertt it into any cheap USB charger and voila.

@scalz said in nRF5 action!:

pretty sure these are the programming pads

they are even "labeled" on the x-ray picture below

@neverdie ...and some nifty soldering skills in order to connect to SWDIO/SWDCLK pads

@alowhum my understaning, it should work out of the box

@neverdie https://www.aliexpress.com/store/product/Nordic-nRF52832-BLE-4-0-4-2-5-0-USB-UART-BLE-dongle-for-computer/420533_32862480389.html

@nca78 Got it. So it's kinda Arduino Nano, but nrf52-based.

@nca78 I don't recognize any LDO on the PCB while it has USB power supply. How is 5V converted to 3.3v?

another method (although I haven't tried it with Ebyte) is to use BMP with GDB and issue a "erase mass" command

@alowhum I intentionally asked you because I know the problem exists.
You need to erase the chip via Jlink Commander. Neither nrfjprog nor anything alse will work (AFAIK)
Actually, it was @NeverDie who found it in the beginning of his quest with nrf52. "The thing that started it all" (c)

@alowhum did you manage to flash them?

@gohan I am not telling you to buy this. Just a direction.
I've created a PID sous vide machine. It's relatively easy project. SMD oven is absolutely the same. All you need is Arduino, thermoprobe and a relay.

@mars-warrior

something like this:

https://store.reflowster.com/products/reflowster

@mars-warrior it depends on quantities of both PCBs and components on the PCBs.
If you have lets say 10 pcbs with 20 components and potentially will have to do it again, the best bet is get a small oven (kitchen type) with PID regulator.
If you just need 2-3 pcbs with 5-6 componets, hot air gun is your choice.
In my current project, I solder ebyte module by hand (very easy) and then LED, resisttors and capacitors with hot air and solder paste.
Looks pretty neat.

@nca78 BTW, HolyIoT makes a similar beacon but nrf52 based. Should be much more energy efficient. The price is about $7

@neverdie for us - yes. For other folks, I think the advantage is the number of targets it supports and the license. Equivalent Segger costs hundreds of $
BTW, Sandeep added BMP support into his core after I raised the issue

@nca78 I used exactly this guide. Works like a charm.

@alowhum just buy a real Blue Pill (around $2) and convert it into BMP.
Then you''ll get both a programmer and an USB-serial that you can use to get data from NRF52 UART

@neverdie I was thinking about that, but that's not gonna work. Why? The bootloader that accepts OTA has a private key. The key in the software should match the key.

Just curious design consideration, based on my question to Nordic:

https://devzone.nordicsemi.com/f/nordic-q-a/33448/led-power

LED consumption will not exceed 0.5ma if the pin is configured as s0s1

@neverdie AFAIK, they are all heavily glued to meet IPX67

@neverdie read Issues section in Mark Cooks's repo referenced above. He's just committed a PR to support the display.
I need nrf52 to able to use Central role in my projects. For Mysensors nrf51 is pretty adequate if someone wants to create something like a wearable weather station
Everything is in place.

https://github.com/micooke/arduino-nRF5-smartwatches

Mark is a fantastic guy

@alowhum there is a whole "movement" of people who are trying to reprogram them. Key issue is openability (how hard is to open it)
The last easily openable watches are based on nrf51822, but the good thing is that programming pins are easily accesable and even marked SWD/SCLCK.
Search Ali for ID107HR and google for "roger clark smartwatch"
I am yet to find a watch that would be both nrf52 based AND easily openable

@gohan said in nRF5 Bluetooth action!:

The ST-Link V2 I found it on digikey and similar sites for around 18/19€, is it the right one?

Don't do that. Either buy $2 clones or invest into DK or:
https://www.adafruit.com/product/3571

@gohan you mean programmer? Nothing beats DK with jlink.
Other options: jlink EDU, DIY BlackMagicProbe or STLink

Just to close the loop on DC-DC:

Figure 2

@neverdie thx. Why don't you have a capacitor between DEC4 to GND? I can see only 2 inductors, while Nordic power guidelines prescribe an LC filter between DCC and DEC, ie inductors and a capacitor. nrf52dk also has it.

ebyte module is currently on sale at roughly $2.5
Total bargain!

@neverdie thx. What is needed hardware-wise? Two inductors between dc and dec4? Like in your breakout board?

Guys, help me understand: when do I need to enable DC-DC?
My breakout board consists of Ebyte module and a couple of buttons. Battery is CR2450 directly connected to the module.
Do I need DC-DC?

@toyman said in nRF5 Bluetooth action!:

Yesterday, I 've got a mailing from my components' supplier featuring new type of cells, Li-MnO2. The cell has all the features needed for nRF5:

• 1200mah capacity
• 1.8-3.0v range
• low cost (ca. $3)
• 41,0 x 24,5 x 5,2 dimensions and, importantly
• up to 120mah peak discharge current.

The link to manufacturer:

Mhmhmh, a disposable battery that you have to solder I can't see it as a good idea for a node...

well, 1200mah will last AT LEAST for a year (two in real life). I have no issues resoldering 2 joints once a year, given it gives AAA capacity in a much smaller package

Where can i get a Kicad component for Ebyte nrf52832?

@korttoma thx. Do they have a CR2032 slot? Sorry, it's not clear from the pictures

@korttoma do you have an Aliexpress link to them?

@nca78 do you move your fantastic Nmodules to nrf5 platform?

Can the FET withstand continious 2A load? I have one meter long 5050 strip

@nca78 "At first I was afraid, I was petrified" :-), but then I relialized that if "recepting" pads are long enough even plain soldering iron will do.
The solder will just flow under the module provided module pads are pretinned Ias you recommended)

@neverdie frankly, I would revive CR2450 idea. 620mah vs 200mah is HUGE difference

@neverdie said in nRF5 Bluetooth action!:

else go square

if you ask me, go this way given the BT module itself is already beyond the circular footprint

@d00616 everything is working EXCEPT relay control.
So the node is recognized in Domoticz, I can switch it on and off, but the relay just doesn't switch on permanently when I send HIGH to the pin. It switches on and almost immediately off.

The schematic is given. I just don't understand why it worked with BLE core and why it doesn't with d0016's.
I always thought Mysensors is an extension of vanilla nrf5 arduino core.

Need your help, guys. I am trying to reprogram a smart socket based on nrf51 module. The schematic is:

I successfully did it using conventional BT Arduino core (Sandeep's) and I was able to switch the relay on/off.
However, when I tried to use Mysensors ESB5 implementation, the relay just switches On briefly and then immediately Off.
I believe this is because the pin doesn't supply enough current for the transistor to saturate (3.3v/1k=3.3ma).
Questions:
a ) shall I use hwPinMode(PIN, OUTPUT_S0H1)? if yes,
b ) why in non-MySensors sketch a simple pinMode(PIN, OUTPUT) worked?
Does MuSensors implementation overrides Sandeep's definitions so the pin supplies less current?

I would stick with cortex 10-pin connector. Mostly because it's (a) standard (b) a cable can be made without soldering by using IDC connectors and a ribbon cable.
The only downside is height.
Using USB connector for sometging that's not USB is generally a bad idea as it's not foolproof

@d00616 have you looked at https://mynewt.apache.org/?

Is v7 already for CR2477? BOM still mentions CR2032

@NeverDie I haven't ordered yet. Waiting for my paycheck.

Guys, pls. have in mind that Ebyte short NON pa+lna module uses pa+lna pinout.
Took me some time to figure it out

@NeverDie it looks like we found an ideal gateway.
What about the code they provide to activate PA+LNA?
Can it be used in mysensors?

Guys, your best bet is to reflash STM32 Bluepill into BlackMagicProbe.
It's awesome!

@Nca78 Arrow ships free to Russia, but only to companies, not to direct consumers this is linked to the fact they use couriers (DHL/Fedex) and not vanilla USPS.
Have a look at www.shipito.com, it's not the one I am currently using, but Shipito works with the whole world. Pricing might be a bit steep, but I haven't looked at it for a long time.

@NeverDie said in nRF5 Bluetooth action!:

It's too bad Fanstel's shipping rates outside the US are high

No issue for me as I am a using a mail forwarder(s) and I can highly recommend them to others. Bringing nrf52Dk from Arrow to Russia costed me $10 (inter-US shipping is free at Arrow).
I am considering switching to Fanstel modules completely, especially to their PA+LNA ones

@NeverDie Are you talking about MYS or in general? Because, currently there are two completely different approaches to nrf-arduino. One is based on softdevice (or in broader terms, on SDK) while another works direcly with hardware.
For MYS, our only hope is d00616, if he doesn't do it, chances somebody will apapt 52840 to MYS are negligible.
Frankly, MYS don't need it, but that's just my opinion.

@NeverDie Sorry, I meant "BLE implementation without Softdevice"

@d00616 said in nRF5 Bluetooth action!:

when an Arduino port supporting Sketches without SoftDevices is availableI

I doubt it will ever happen as all 3 major nrf5 arduino implementations all rely on Softdevice (Primo, Adafruit and Sandeep)

@NeverDie they even provide a piece of code to properly activate it

@NeverDie the main issue it's "65 commits behind master" so it's outdated in all areas except 840
Theoretical path is to make a fork of current sandeep's branch and then merge the changes from the repository you found. But given the above, it won't be easy.

@NeverDie said in nRF5 Bluetooth action!:

Their pinout on the 832's does not appear to be as complete as the Ebyte module, so if DCDC is not already on the module, it might be impossible to add after-the-fact.

https://static1.squarespace.com/static/561459a2e4b0b39f5cefa12e/t/59a5a0bbbe42d6d26bd82969/1504026813812/BlueNor_BT840F_datasheets.pdf

Page 13,
pin F5

@NeverDie exactly! On top, they have very extensive datasheet with all the results

@NeverDie actually, I am suprised that many of these modules are available and at the prices lower than Ali.
For example:
http://www.fanstel.com/buy/bt832xe
They claim "BT832XE is the longest range Bluetooth 5 module, 1350 meters between 2 BT832XE with used with ANT060 antenna."
$23, shipped within US
Not bad, ah?

@NeverDie I believe, buying non-Chinese modules in retail is virtually impossible, but Xuntong, Skylab and Raytaq are available at Ali.
For me, the list is more like "quality assurance"

Guys,

Have you seen this?

Note, that our beloved ebyte is not there, but PTR9618PA is

@d00616 said in nRF5 Bluetooth action!:

Yes. Give the event register as parameter.

so, if I have an intterupt atached to pin 1, what shall i put into ISR?
NRF_RESET_EVENT....;
Sorry for dumb questions, this is completely new to me.

@NeverDie should it be placed just before hwSleep()?

@NeverDie do you use hwSleep() instead of sleep()?

@d00616 thx. How do I use the macro? Just put in ISR?
Regarding the bug: if read the docs correctly, all nrf51 have the bug

@NeverDie wait, d00616 code is basically an extension of Sandeep's. The Sandeep's code (should) supports 8 interupts for nrf52 and 4 - for nrf51.
At least, that's what I conclude from here
Assuming it works, the next question is: can I put just ANY pin into attachinterrupt() function or not?

What's the proper way to deal with interrupts on nrf?
Many white areas:

• shall I use "smartsleep()" instead of usual arduino way of attaching interrupts? is it enough?
• what pins have hardware interrupts? any?
• what about the macro mentioned in d00016 readme?
• how to overcome nrf51 bug of 1ma power consumption (code-wise)? Otherwise I see no reason buying nrf51 modules if they consume 1ma while sleeping

I thoroughly read al the docs before asking!

@d00616 not supported by 52810

@Nca78 cool, thx

@d00616 absolutely excellent summary, thank you.We definitelly needed some kind of "what do we know so far"
Is it confirmed that the range and power consumption are on par with 328+24L01 combo? I don't mean any "scientific" proof, but something like "I have placed nrf52 node at the same location in my house as nrf24 node and had no issues"
I am awaiting components to make "u-current meter" and test current consumption by myself

@NeverDie said in nRF5 Bluetooth action!:

you can buy it on a breakout for around $2.50

do you have an example? The lowest I can find is ca. $4 (incl.S&H).
Don't get me wrong, $4 is more then adequate for 328+24L01 replacement, but $2.5 is even better :-)))

What about "long-range" iBeacons like Skylab or RedBear ones? Do they have some kind of PA or their "long-range" is just a marketing gimmick?
