and for Rx
AT+UBTLECFG=28,3
Connect two NINA-B31 according to the use case in section 4.1.
When the connection is established, request a new PHY configuration for the connection (Device B)
•
Go to AT mode by sending the escape sequence:
1.
Silence 1 second
2.
+++
3.
Silence 1 second
•
Request 2 Mbps PHY for both Tx and Rx on connection with handle 0
AT+UBTLEPHYR=0,2,2
•
If the remote device (Device A) accepts the request, a successful event will be received
+UUBTLEPHYU:0,0,2,2
