Direction_finding_tx problem

user116169

Hi,

I have two nRF52833 and i want to make one tx and one rx (with an antenna array) for direction finding (AOA mode).

I have already compile the project called "direction_finding_connectionless_tx" and put it in my device by using SEGGER embedded studio but i have two problems.

1) How can i be sure that the program is in my device because the program don't put a LED on.

2) If the program is well implented i don't understand why my nRF52833 doesn't advertise (because when i use nrf connect for mobile my transmitter are not seen, there is no emission).

If you can help me i'm more than interested :)

    Hi

    Are you using a custom board or a development kit?

    1) How can i be sure that the program is in my device because the program don't put a LED on.

    I suggest that you edit the code to turn on a LED yourself. See for example the DK Button and LEDs library.

    Or even better, you can use logging to print data to a PC using a serial connection.

    Another alternative is to debug your program using a debugger. See nRF Connect for VS Code, 5: Debugging.

    2) If the program is well implented i don't understand why my nRF52833 doesn't advertise (because when i use nrf connect for mobile my transmitter are not seen, there is no emission).

    Does your program freeze/loop forever or return any error codes?

    Regards,

    Thank you very much for the reply.

    So first i use the serial connection to verify that the device return all the printk as "success" and that's the case so my program was well program into my device.

    After that i check with a bluetooth analyszer if my device advertise well and all was OK. Unfortunately, my analyzer doesn't allow me to see the CTE.

    So i think i will program the receptor to see if the CTE is well send :)
