BLE stack 2.2.1 Serial port over BLE

Other Parts Discussed in Thread: CC2650STK

Hello.

How to use CC2650STK (ble stack 2.2.1) with serial port (SPP) over BLE?

We are using SPP with stack 2.1 and good working, but on 2.2.1 stack this incorrect work. 

I think problem in MAX_NUM_PDU parameters. In stack 2.2.1 queue = only five elements, that is why we are have lost packets...
