The running of the CSR Bluetooth Chip SPP service is the PS setting, csrspp

The running of the CSR Bluetooth Chip SPP service is the PS setting, csrspp

The CSR Bluetooth chip directly runs the built-in spp_dev_ B example program. The host cannot search for Bluetooth devices, mainly because the PS key value needs to be configured as follows:

This item is actually set the matching code for the connection. It will be changed when the program runs without modifying it. Here I am 8888, so we need to enter 8888 during pairing.
