Exemple programare
Standard Uart interface is used to configure the parameter of SA818 Walkie Talkie. The format of UART is 9600, 8, N, 1, which means: Baud = 9600, data bit = 8bit, Parity = None, Stop bit = 1 bit. The interface is TTL or CMOS @3.3V. The parameters which can be configured are: Bandwidth, Tx-frequency, Rx-frequency, SQ, Tx_SubAudio(Tx_CTCSS/ Tx-CDCSS), Rx_SubAudio (Rx_CTCSS/Rx-CDCSS), Volume, Scan frequency, Audio filter, etc. When commands received, the module will verify and reply acknowledge message; User should wait enough time to send the next command until received the acknowledge signal.
AT+DMOCONNECT
AT+DMOSETGROUP=GBW,TFV, RFV,Tx_CTCSS,SQ,Rx_CTCSS
. GBW: Channels space. 0.12.5k; 1.25k . TFV: Transmit frequency. Range: 134.0000~174.0000MHz . RFV: Receive frequency. Range: 134.0000~174.0000MHz. The frequency should be the times of 12.5KHz or 25KHz. . Tx_CTCSS: CTCSS value in transmit PL103.5 = 13, PL123 = 18 . SQ: Squelch level (0~8). 0. monitor mode which can.t be used in scanning mode. . Rx_CTCSS: CTCSS value in receive PL103.5 = 13, PL123 = 18 . x: Configuration result. 0. succeeded; 1. data out of range.

By default Raspbian configures the Raspberry Pi serial port (GPIO14-GPIO15) to provide boot-up information. It also allows you to login via a connected device. If you need to use the Pi’s serial port for something else (i.e. a specific add-on board) you will need to disable this default functionality.
