nRF5 action!

You mean way more complete every thing is accesable there and there is an example for everything and I didn't use my sensors anyways

No. I mean if you want to use the Nordic MCU with BLE and you want to access the whole hardware without developing drivers, then the Nordic SDK is an option. For special requirements like tone() you have to develop your own routine for Arduino or SDK.

If you want write code which is compatible with other Vendors or want use MySensors then the SDK isn't the best choice.

The arduino-nrf5 targets to provide the Arduino language. I think this is mostly complete. MySensors brings additional support for enhanced pin output modes and the random number generator (no SoftDevice support here).

Accessing the internal MCU hardware must be added via Arduino libraries. With the new SDK license I think it's possible to put parts of the SDK into libraries supporting Hardware which is not specified in the Arduino reference.

If you want to develop BLE applications with portable code, there are open source implementations like http://mynewt.apache.org/ which are designed to be portable.

Good news! The hwCPUVoltage() function measures the Vcc voltage on the Ebyte module in millivolts. I'm able to send that as a barometer reading using the mocksensors sketch, and it arrives all the way into Domoticz, where it is logged and graphed. So, obviously I need to streamline that a bit, but the proof of concept works.

NeverDie

Quantization error on the hwCpuVoltage() function appears to about 14 millivolts, which is a nice little improvement over the atmega328p. Measurement accuracy appears to be well within those bounds.

Next step is to measure voltage on an analog pin using an AnalogRead. Not sure if the reference voltage is Vcc (as it typically is with the atmega328p) or something else for those measurements.

Given new Arduino Primo contains a buzzer connected to nrf52, we might expect tone() function to be compatible with nrf52 very soon

Strangely, if I do, say, analogRead(A4) on the nRF52832, all I get back is a 10-bit number, not a 12-bit number. i.e. the number never exceeds 1023. That can't be right. Should I be using a different function call to get the full 12 bits on the nRF52832?

@NeverDie looks like you need to call analogReadResolution first https://github.com/sandeepmistry/arduino-nRF5/blob/425e719af8d85b543def01e49a6ef4048525dc59/cores/nRF5/wiring_analog.h#L74

Thanks! That did the trick. Calling analogReadResolution(12) once in Setup() routine, I now get back a 12-bit number (i.e. up to 4095) thereafter when I do an analogRead(...).

NeverDie

So, just did the experiment, and here are the results. Supplying 3.3v to the Ebyte Module, a voltage of 3.0 volts on A4 yields an analogRead(A4) of 4095. Less voltage on A4 yields a lower number.

So, generalizing, I suspect that the reference voltage for analogRead() is Vcc-0.3.

So, you either know Vcc, because of a voltage regulator or something, or else you must call hwCpuVoltage() to get what it is. Then, subtract 0.3v from that, and that's the reference voltage which corresponds to an analogRead() return value of 4095.

I just did a quick and dirty measurement on the current consumption of the nRF52832 Ebyte module during sleep, and it measured 10 milliamps. I measured it using a uCurrent Gold. That's very high current for most battery powered applications. Can someone else here please measure it also and either confirm or refute?

I invoked sleep with this from the mocksensors sketch:

	wait(SLEEP_TIME); //sleep a bit

Perhaps there's a way to invoke a deeper sleep than that where less current is drawn?

rmtucker

@NeverDie
Try

sleep(60000); // Sleeps for a minute in deep sleep

NeverDie

@rmtucker said in nRF5 Bluetooth action!:

sleep(60000); // Sleeps for a minute in deep sleep

Thanks! That's a big improvement. I'm now reading 51uA. I did the measurements on the Ebyte nRF52832 module, powering it at 3.3v.

However, to be frank, that's still rather high compared to, say, an atmega328p with a RFM69 radio, which can have a combined sleep current of less than 1uA.

Is there anything more that can be done to lower the sleep current further?

rmtucker

@NeverDie

Is that a bare board with nothing connected (Not even serial)?

Yes. It's the bare Ebyte nRF52832 module. The only connections are Vcc and GND.

rmtucker

@NeverDie

Theoretically it should be around 1.9uA

NeverDie

Interestingly, I just now tried the same measurement with one of these nRF52832 modules instead of the Ebyte module:
https://www.aliexpress.com/item/nRF52832-Bluetooth-4-1-BLE-Module-M4-Transparent-Transmission-SMA-512K-FLASH-64K-RAM-pass-through/32798522093.html?spm=a2g0s.9042311.0.0.KKA3PF
and during sleep it measured 6uA. Quite a bit lower!

Anyone know of a module which tests even lower than that?

Did you use the same board definition in the IDE and the same script ?

Have you tried sleep and wait for an external interrupt instead of sleep and wake on timer?
Just in case it is the lfxtl that is causing the problem.

Haven't tried that yet. Is there a library functional call for that, or do I need to start addressing the registers directly? With this new mpu, I feel like I'm learning to walk all over again.

rmtucker

@NeverDie

Try

sleep(digitalPinToInterrupt(10), FALLING,0);

NeverDie

@rmtucker said in nRF5 Bluetooth action!:

@NeverDie

Try

sleep(digitalPinToInterrupt(10), FALLING,0);

Unexpected result: using that as the sleep invocation, the infor-link module measures at 14ua while sleeping. i.e. worse, not better, compared to the 6ua measured earlier.

NeverDie

Looks as though the infor-link is using an A620N crystal:

I tried to see if I could find a datasheet for it, in the hope of learning what its current consumption is (or, at least, should be). Unfortunately, though, I couldn't find a datasheet for an A620N.

NeverDie

Maybe it doesn't matter, because in looking at the actual module I received, it appears to use a different XTAL anyway: A649N.

NeverDie

Maybe from a current consumption standpoint, not using an external XTAL crystal, but rather relying on the nRF52832's internal resonator would draw less current? I know that's true for the atmega328p. If so, then that's a trade-off worth examining more carefully.

@NeverDie

Sorry i have been a little distracted because my waveshare BLE400 and jlink just turned up.
Took a little time to get it running but i loaded up the mockmysensors sketch with all the sensors un commented and pow all 30 odd sensors showed up in domoticz which made me chuckle.
Anyway post your sketch for the consumption testing and i will put it in and see if it works on my board.
The only problem is i can not unplug it from the Ble400 because i have no way of connecting wires to the core board because of the smaller pitch pins.

You'll need a separate serial gateway running for it to communicate with, or else it will never get to the section where it sleeps.

@rmtucker said in nRF5 Bluetooth action!:

The only problem is i can not unplug it from the Ble400 because i have no way of connecting wires to the core board because of the smaller pitch pins.

For the current measurement, just program it with the above sketch on your Waveshare, then unplug your module from the BLE400 board and power it using a GND dupont wire and a Vcc dupont wire connected through your uCurrent Gold, or whatever it is that you're using to measure current. I should think that would work, wouldn't it?

alt text

Or do you only have the main board without the smaller plug-in module?

It actually looks like a nice setup.

rmtucker

@NeverDie

When you unplug the little board it only has 1.27mm spaced pins and they are not standard dupont size so shy soldering to them which would mean i could not plug it back in to the BLE.
Anyway i am only using a crappy multimeter and with it plugged in and running your sketch i am getting 140uA but i will find a way of unplugging it so hang fire.

Nca78

@rmtucker you could try to just solder 2 tiny wires on top of the board for vcc and gnd pins so you don't mess with the connectors for plugin it back on the main board ?

NeverDie

@Nca78
Agreed. It sounds as though the bigger problem is going to be his crappy multimeter, if that's all he has. Maybe a good time for an upgrade?

rmtucker

@NeverDie
Ok with my crappy multimeter i am getting 4-5uA with just Vcc and Ground connected.

NeverDie

I'll try removing the 32.768Khz crystal from an infor-link module and then re-run the sketch that relies on an external interrupt to wake from sleep. Maybe that will get us closer to the theoretical minimum current of just the nRF52832 chip by itself.

rmtucker

@NeverDie
Just a little thought on this and a bit of googling.
Just the system on consumption is 1-2uA without the rtc that is needed for wakeup so i don,t think the figures we are getting are that far away from the spec sheet?

So, generalizing, I suspect that the reference voltage for analogRead() is Vcc-0.3.

The internal reference is 0.6V the nRF5 MCU's have an internal programmable divider. With Arduino this divider is programmed to 1/5. If you switch to the external reference the "gain" is 1/4.

I measure with my CDEByte 11-15µA for sleep without interrupt waiting. With a RedBear BLE Nano 2 I have measured 15µA. Both compiled as BLE Nano 2. I have used the VC165 multimeter.

Seems like there's more than one library named "Wire" that's floating around at the same time. I wonder if perhaps the compiler is finding the proper Wire library inside Arduino-nRF5? Or maybe it's linking with an unrelated Wire library? To answer that, you could try inserting a Serial.println() into the proper library and see if it fires off when you run your code.

This is strange: now when I do the timed sleep on the infor-link module, it shows a current drain of about 60ua, whereas yesterday it was around 6ua. Maybe I somehow damaged it by connecting a couple of the input pins (A2 and A4) to Vcc? I wouldn't think so, though, because the datasheet says it should be safe to Vcc + 0.3v.

I have one unused infor-link module left. I'll try wiring it up, but without the input pins this time, and measure it. I'm wondering now whether the sleep current will measure out to be 60ua, or 6ua.

The answer is.... neither. This time, with a fresh infor-link module, it measured at about 16ua.

However, I'm guessing there's quite a lot of noise involved, because this time I noticed I could change the reading just by moving my hand closer or further away from the infor-link module. So, I may have to scope this to see what's going on.

On the 10F supercap, the infor-link module was losing about 0.025v per hour, and that included it reporting its voltage every 5 minutes. So, I've hooked it up to a mini solar panel now so that the supercap will charge during daytime, and with that it should run in perpetuity.

I did another sleep current measurement, this time on a Ebyte module that I had mounted to one of my breakout boards. The sleep current measured between 8ua and 9ua. However, it would jump considerably higher depending on whether I was moving or otherwise close to it. I got the lower measurements by positioning myself about 6 feet away (further than that and it gets hard to read the multimeter that's connected to the uCurrent Gold). I've never seen this kind of behavior before in anything other than the nrf52832 boards. Very curious. They're acting almost like proximity detectors. I have no idea what to make of it, but I thought I'd report it in case anyone else here is doing measurements too.

Also, I'm going to avoid exposing the IO pins to voltages that approach Vcc in magnitude. Despite what the datasheet says, they don't seem to handle it well.

mtiutiu

@rmtucker

Even if you're not using the regulator and the CP2102 usb-serial converter there are some leakage currents which are caused by the output stages of those IC's. For example the output stage of the voltage regulator can draw some even if it's not powered. The CP2102 can draw also through the TXD1/RXD1/SUSPEND1 LEDs and the associated GPIO pins P0.11, P0.09, etc.

So to prove and test that the above it's true you need to:

Desolder the RT9193-33 or at least its output pin(Vout pin 5)
Desolder R6, R7, R10

This is what I can conclude by looking at that schematic. Any other opinions?

I have a Fluke 87V, and I don't trust it to do these types of measurements (I've tried, and the results are just wrong when compared to a uCurrent Gold). I would trust a crappy multimeter even less. Been there and tried that already.

Just my two cents.

BTW, uCurrent Gold is open source. I have an original, but you can buy clones. For instance, LowPowerLab sells a clone. You might get it faster than ordering from Australia.... unless you live in Australia. Dave Jones did a video for me once, and so I thought he deserved the profit instead of somebody else.

It just depends on the burden voltage, no ? It's proportional to current in the circuit so in sleep mode when measuring around 10 uA it should be negligible.
Anyway I measure when powered with 3.3V so I'm sure what I measure is higher than what I will get in reality when circuit is powered with a 3V battery.

For measuring small currents I'm using Texas Instruments EnergyTrace piece of technology and it works pretty well. You just need one of their development boards with energytrace special microcontroller embedded which is very cheap. More infos here: http://43oh.com/2015/09/how-to-measure-an-energia-applications-power-usage-with-energytrace/

It can be used to measure other boards power usage also - you just need to take of some jumpers and plug in your external board.

It gives you real time energy measurements and with plotting too(and battery life estimation is displayed real time too). No need to worry about burden voltage and other external factors which affect the measurements.

@mtiutiu
I think maybe the nRF52 DK also has some energy measurement capability, but I haven't looked into it.

Looks like I was wrong earlier about the voltage reference being Vcc when doing an analog read on a pin. Instead, it seems to be a fixed reference. In any case, I'm getting better results with an expression like this, which is independent of Vcc:

millivolts = (analogRead(PIN)*3000/4095)

What are others here doing in this case?

@NeverDie
As mentioned earlier by someone the nrf52 is preset to 0.6v internal ref and a 1/5 divider so 0 - 3v is the max input so your calculation is correct.
The nrf51 is different because the ref can be set to a few different settings but the default is vdd.

Is RSSI reporting implemented in the NRF5 setup yet?
If so how is it done?

scalz

I don't think sendSignalStrength function is implemented yet, but you should be able to get this info with:

int16_t transportGetSendingRSSI(void)
int16_t transportGetReceivingRSSI(void)

How can I redefine UART pins in nrf51822? For example, if I want to have p13 as uart tx?

scalz

@Toyman
it has been explained above in the topic
you have to follow

rmtucker

@scalz
Rssi works really well.
Thank you.

rmtucker

So range test.
Using esp8266 with standard nrf24 not amplified gateway at one end of the house.
Nrf51822 node in garage which is not fastened to house so at a guess 15m through 3 brick walls is reporting -86db.
I think that is quite respectable.;-)

@scalz thx.

Regarding the PCB/KiCad comments.
I was trying out KiCad and copied the NRF52832 DC/DC schematic from the datasheet.

It might be of help for someone.

PS. been at KiCad for a couple of hours, been used to Eagle, so please double check.

I've lately found that I seem to get a more accurate measurement if I multiply by 3131 instead of 3000. Just an empirical result with no real theory behind it.

I don't know if it is actually related, but I'll post the link to this programmer

What's going to be the best way to reduce the sleep current and Tx current on the nRF52? Since I'm feeding off a supercap for power, it's noticeably worse (by an order of magnitude) on the same task than the atmega328p+rfm69 combo. I've already increased the datarate to 2mbps, and it's inherently lower Tx current should give it a natural advantage.

I guess I'll try reducing Tx power and see if that makes much of a dent....

I suppose reducing 3 separate packets to one single packet, and maybe turning off ACK requests might also help. Then, maybe all of the LONG_WAIT's can be eliminated. Is the radio still awake even if the CPU is sleeping during a "wait" period? If so, that might be a large chunk of the wasted power.

I wonder if the mysensors mesh networking (which I don't intend to use) might be getting in the way, and possibly keeping it awake longer than it otherwise would be? Can I disable the mysensors meshnetworking just to be sure?

Sorry for the shotgun blast of questions, but I'm trying to get a sense of what will yield the highest payoff.

NeverDie

Since I'll be reducing Tx power in an attempt to reduce current consumption, I'll be using a scanner program to try to find empty channels. The only one I know of is: https://github.com/nRF24/RF24/tree/master/examples/scanner
for the nRF24L01, but it seems to work well enough if you let it run awhile. Anyone else using one that they like?
