BLE DISCONNECTION PROBLEM

[Nasib]

Hi, I am using the UART over BLE example + a timer interrupt + a pwm signal. And I am facing the following problem (error launched by my phone app: )



This happens sometimes and with different apps, so somehow sometimes there is an issue during the connection. 

Can you identify this problem? 

Thanks a lot .

Hi

This is mentioned on multiple other forum threads with the "GATT error 133" subject. Try adding a delay before connecting to GATT.

Best regards,

Simon
