Where did you get that small nrf52832 module? -

@NeverDie I guess you don't need to make a breakout board for those, your spare NModules will do if you use the "PA/LNA" radio footprint ;)

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.@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.

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.

@Mike_Lemo could you be slightly more specific than "doesn't work"?

apparently it doesn't recognize it says tone wasn't declared in this scope
That's how the line looks tone(BUZZER_PIN, BUZZER_TONE);
BUZZER_PIN = 26
BUZZER_TONE = 3000 -

@Mike_Lemo it (the tone library) would need to be ported

@Mike_Lemo it would need to be ported
No idea what you are talking about.

Some further evidence in support of this hypothesis (from: https://github.com/mysensors/ArduinoHwNRF5):
Most components, like UART, SPI, Wire Bus, of the nRF5 series chips don't have a fixed pin mapping.

@Mike_Lemo look it up? https://en.wikipedia.org/wiki/Software_portability#Effort_to_port_source_code
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.
