Hi there,

I am trying to test how the OTA works using the "hr_sensor" example on the starter Kit module. The code is compiled and upladed using Bootloader V7. Then  I use the app CSR uEneergy OTAU v1.2 on Android phone . Open this app, load the file and select the BLE device.

The process starts with GATT erver connection , reads CS blocks 
Enter OTAU bootloader mode -> Disconnects
GATT server connected and service discovery completed 
Read crystal trim value error!! 

thats the sequence of events on the log file.


I have tried several things like changing the Bootloader version to V6 or changing some user Key values but it always fails at the same point with the message : Read crystal trim value error!!
Any suggestions what could I try or why this is happening?
thanks in advance
