problem with advertizing in every BLE solutions

[ali_dehghan_nayeri]

Hi all. I hope you having a healthy day.

I am a beginner with nrf52 dev. I want to implement the BLE hrs on my custom board. My board doesn't have any optional modules.

It has just NRF52832 and some resistors and one led :). (without any external clk)

It can also connect with JLink. 

So now I have done the works listing below:

1- download segger and active that 

2- download SDK 17.0.2

3- open hrs ble app in segger

4- build and download to NRF

In my central app (android NRF connect), I can't receive any advertising data. I have debugged the code and put NRF_LOG_INFO in code but the code was executing without any error.

I have just tested the blinky app and turned on and off my only LED successfully.

--) I tried to connect with desktop NRF Connect to the device, but I got some errors.

--) I saw some Q about changing clk to src_rc clk but it didn't solve the issue.

So now what is the scenario to implement ble hrs app?

thanks a lot.

You will need a lot of external circuitry (see reference design) for this to work with BLE:
