6.1. How to Send AT Commands
⚫
When BT is NOT connected (for all commands)
1. Output low to P0.10 (UART PD pin) to enable UART interface. Please keep it enabling
during the whole time when sending AT commands.
2. Send any AT commands you want.
3. S
end command “ AT+RESET ” to save all your settings.
4. Output high or NC to P0.10 (UART PD pin) to turn off UART interface.
⚫
When BT is connected (for AT?ADCVALUE, AT+DISCONNECT,
AT?CONNECTRSSI, AT+SCANNEWSTART and AT+SLEEP only)
1. Output low to P0.11 (flash default pin) to enable receiving AT commands when BT is
connected. Please keep it low during the whole time when sending AT commands.
2. S
end “AT?ADCVALUE” or “AT+DISCONNECT” or “AT?CONNECTRSSI” or
“AT+SCANNEWSTART” or
“
AT+SLEEP”.
3. Output high or NC to P0.11 (flash default pin) to disable receiving AT commands when
BT is connected.
