Before programming the SA818 module, make sure you consult the band plan for your country and transmit on a frequency you are allowed to use.
The easiest way to install is program is to use the command pip. Pip
will automatically take care of installing the dependencies.
$ sudo pip install sa818
You can also clone this repository and use the setup.py script with
the following command. You will have to install the python package
pyserial manually. To install dependencies, refer to the manual of
your operating system.
$ git clone https://github.com/0x9900/SA818.git
$ sudo python3 setup.py install
[root@allstar ~]# sa818 version
SA818: INFO: Firmware version: V4.2
[root@allstar ~]# sa818 radio --frequency 145.230 --offset -.6 --ctcss 100
SA818: INFO: +DMOSETGROUP:0, BW: Wide, Frequency (RX: 145.2300 / TX: 144.6300), CTCSS (TX: 100.0 / RX: 100.0), squelch: 4, OK
[root@allstar ~]# sa818 volume --level 5
SA818: INFO: +DMOSETVOLUME:0 Volume level: 5, OK
If you use an FTDI dongle to program the SA828 module the USB port can
be specified with the --port argument
[root@allstar ~]# sa818 --port /dev/ttyAMA0 volume --level 5
SA818: INFO: +DMOSETVOLUME:0 Volume level: 5
It is possible to specify a different CTCSS or DCS code for transmit and receive by separating the two codes by a comma (no spaces). For example, --ctcss 100,88.5 will set the CTCSS 100Hz for transmit and 88.5Hz for receive.
This program has for sections:
- radio: Program the radio's frequency, tone and squelch level
- volume: Set the volume level
- filters: Turn on or off the [pre/de]-emphasis and as well as the high and low pass filter
- version: display the firmware version of the SA818 module
