    Why can't I use peripheral and HCI UART reliably at the same time ?

      There is an issue when both UARTs are used at the same time at lease with TAG3 (with 20737).


      I noticed that data in peripheral UART sometimes gets corrupted.

      This never happens when running in HCI mode, but happens in APP mode (when HCI UART is used for debug).

      I narrowed down the problem to the ble_traceX function.

      The more ble_traceX are executed the more chances for a corruption on peripheral UART.

      This happens only sometimes but it is easy to reproduce.


      Any suggestions ?
