nRF52832 to mobile phone via BLE

[Sai Kiran]

Hi

Can anyone tell me which example in SDK to use to send data(a simple text message) from nRF52832 board to an Android Phone. I have nRF Connect and nRF Tools applications installed on the phone.

Thanks in advance.

Hi.

I am using 15.3.0 version of SDK. I am just using the nrf_app_blinky example. I have not changed anything in that. So, hex file that I am using is the same as the hex file in the SDK. I am using s132 softdevice and Segger Embedded Studio v4.10.

As far as I know, there's 32kHz crystal on the board. I tried making the change you suggested regarding NRF_CLOCK_LF_SRC_RC. When I do that, the LED1 does not glow, which means that the configuration is wrong. And hence, I switched back to the previous configuration.

Here's the pic of the board-

It seems that the board has been reworked especially the components around the chip. C3 is also missing. 

I would suggest you to test using another board. 

You can also step into the code to debug and check where it assert. You can follow the debug guide here.

Yeah, got it. I have connected the custom board to DK and it is working. However, I have some issue while observing the log output using Putty. Previously, using Putty, I was able to observe the Log values. Now, when I use the custom board, I am not able to observe the Log Output.

It's because you don't have the connection of the UART pin to the Segger chip on the DK. If you connect the UART pins of your nRF52 on the custom board to correspondent pins on the DK (TXD to P0.06, RXD to P0.08, RTS to P0.05 and CTS to P0.07) it should work.
