Can't get the code to run - to boot into main

Have you done any antenna tuning on your side? Usually when a custom board's radio doesn't work as intended it's usually due to poor RF performance because of improper tuning or PCB design. You can create a private ticket where you upload schematics and PCB design files for us to review to ensure the HW design looks ok.

Hi, Thank you.

another problem on my custom board is, that I can not recieve the RF data sent from this custom board, I have dev kit where I can recieve data sent from another dev kit, but when I transmit the same packet from my custom board - no data are recieved. I tried to debug my TX routine on custom board and it seems everthing works fine - after start TX I got to IRQevent handler

void radioEventHandler(struct esb_evt const *event) where

event->evt_id is equal to ESB_EVENT_TX_SUCCESS

When I got this event, does it mean the data was really transmitted? If yes, why I can not receive tha packet as from dev kit? (the packet and RF settings should be the same - I used the same code)

Thank you very much.

Indeed, the problem does sound like this is because the external 32.768kHz LF crystal is not mounted on your design. By default, our sample projects use the external LF crystal, and you will indeed have to config the clock to use the internal RC oscillator instead to run applications on designs without this crystal. It looks like you've found the correct solution to your issue. Let me know if you run into further issues, and we can take a closer look!

So I added this to my prj.conf, now it works but do not know if this is correct waý to solve the problem.

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
