Hi,

I have tried mesh on-off sample program on nRF52 DK with and without using crystal and it works fine. I am able to provision nRF52 DK using bluez.

When I try mesh program on Fanstel BT840F evaluation board with crystal, I am able to provision BT840F. But when I disable by crystal by adding these below lines to my prj.conf, I am not able to provision. I am able to see it as unprovisioned node which means advertising is fine but not sure why provision fails. Any quick help/hint on debug is appreciated. BT840F is nrf52840 based and nrf52 DK is nrf52832 based. As RC is internal to SoC, I am not expecting any issues with DK or EV as they are working fine with crystal. I am using nrf52840_pca10056 as board definition.

Is there anything wrong in configuration for nrf52840 as compared to nrf52832 in relation to crystal?

prj.conf:

CONFIG_CLOCK_CONTROL_NRF5_K32SRC_XTAL=n
CONFIG_CLOCK_CONTROL_NRF5_K32SRC_RC=y
