CC2541 (Master UART) - CC2541 (Slave UART) Serial Port Transparent Transmission Experiment [Copy link]

Power-on status: slave actively broadcasts, host scans and connects to slave through AT command
AT+SCAN scan
AT+CONx x is the scanned device serial number, connect the xth device
After the connection is completed, two-way transparent transmission can be performed

In addition, there are many AT commands that can be used
AT serial port test, return OK
AT+ROLE? Get the current role
AT+SCAN scan slave
AT+CON[x] Connect to the specified slave, x is the searched slave serial number
AT+RSSI Get rssi value
AT+DISCON Disconnect
AT+BAUD? Query serial port baud rate
AT+BAUD+xx set 1-5 set baud rate (valid after power on again)
