My app is not working on all nrf52810 existing modules

Hello, I developed a simple advertising application first on nrf52832 with succéss and I'm trying to adapt it to nrf52810.
I therefore switched from S132 to the S112 softdevice and the application works on the NRF52DK dev board, but also on a "Minew" MS50SFA module (with 32.768 Khz crystal).
On the other hand, on a "MOKO - M2" module which does not have this crystal, it does not work!
I however modified the lines corresponding to the presence or not of this crystal in the sdk-config.h!
What did I forget?

I'm working on SEGGERS

Thanks for your help
