Sir,
How are you ?
I developted an BLE application (Segger Nordic SDK) to a chinese module and worked very very nice! I installed in 40 modules. All working
No i ordered 50 units of the same module, but i see a difference, no more external 32Khz crystal.
On this module, my application does not run more!

Look at! Right is equal to Left, but no more 32Khz :(
What am i have to modify in my software to be alive again ?
Thanks!
