Hi,

HW: TI CC2745R10-Q1 EVM (car node) and a mobile phone

The car_node project default pairing code is123456, and the pairing mode is: Initiate a pairing request.

How to reproduce:

The TI CC2745R10-Q1 EVM complete pairing binding with mobile phone for the first time, and reflash TI CC2745R10-Q1 EVM, at this moment, the passkey is lost. (This is under expectation since we didn't protect flash) 

Then the mobile phone reconnects to the TI CC2745R10-Q1 EVM and a pop-up prompt to enter the passkey will appear. The passkey is also entered as 123456, the status of the TI CC2745R10-Q1 EVM pairing completion prompt is not successful and the return value is 0x08.

Please help how to solve this issue if the phone does not actively clear the passkey
