Two projects send log messages through UART. After starting, the PTU project logs Advertising and Scan response

reports from the PRU, for example:

Advertisement report: peerBdAddr -00 a0 50 e1 61 a8 , rssi - -36 dBm, data - 02 01 05

07 16 fe ff 0c 00 a0 00

The PTU automatically connects with the advertised PRU. Observe the initialization procedure. The blue LED on

PRU indicates charging. After Vrect reaches VrectHighDyn, the PRU sends the simulated Alert Notification with the

Complete Charge status and switches off the blue LED.

The output of the debug serial port looks like the sample below:
