nRF52840 not advertising

[carl hong]

nRF52832 PCB designed by myself can work normally， change chip to nRF52840  not advertising(Phone can't scan)

[carl hong]

I use example  of "ble_app_uart",  modfiy clock_lf_cfg, 

NRF_SDH_CLOCK_LF_SRC 0

NRF_SDH_CLOCK_LF_RC_CTIV 16

NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2

NRF_SDH_CLOCK_LF_ACCURACY 1

Hi,

Could you explain this a bit more in detail?

What do you mean by this? Please specify, so I can suggest a solution to the problem :)

I've determined that it's a hardware design problem. The software is normal. Maybe it's an antenna problem

Again, i'm still not sure exactly what you're trying to do. Could do another attempt in explaining your problem? It seems that you have designed a nRF52832 based custom board and are now trying to change the IC with a nRF52840 on the same custom board. Please verify.
