Setup Modules

Doodle Labs module setup parameters need to be same for both Doodle labs radios (in UAV and wearable).

Those parameters can be setup manually, or by copying and running following script:

https://github.com/airvolute/airvolute-doodle-setup/blob/main/radio_communication_setup.sh

If you want to use the script, first copy it into the modules, modify desired parameters and run it.

The script should set frequency, channel, bandwidth and it should restart doodle system services. After running the script, you can power cycle radios to be sure.

Script contains uci commands, that can also be used in Doodle Labs terminal manually.

Setting frequency

To set frequency, you can use command:

uci set system.@system[0].submodel=<freq_id>

Example:

uci set system.@system[0].submodel='RM-2455v3-2L-X'

To set frequency, you need your desired frequency value and submodel of the radio. Submodel is presented as suffix in <freq_id> string. For example, in string 'RM-2455v3-2L-X' , which is an example above, suffix (submodel) is v3-2L-X.

You can check your submodel by using command uci show | grep submodel. Example output:

root@smartradio-301a39c846:~# uci show | grep submodel
system.@system[0].submodel='RM-2455v3-1L-X' <<<<

The second line is output of the command uci show | grep submodel , from where you can extract submodel, which is in this case v3-1L-X.

Now you can set freq string by combining your desired value and submodel into one string. Let's say, you want to set the frequency to 2400 MHz (fictional value) and your submodel is v3-1L-X. The final command will look as following:

uci set system.@system[0].submodel='RM-2400v3-1L-X'

Setting bandwidth

To set channel bandwidth you can use command:

uci set wireless.radio0.chanbw='26'

Don't forget to apply changes and restart Doodle system.

Setting channel

To set channel you can use command:

uci set wireless.radio0.channel='51'

Don't forget to apply changes and restart Doodle system.

Applying changes

To apply changes use command:

uci commit

Now restart Doodle system services using:

wifi

You can evaluate your settings using:

uci show

You can filter output using grep, for example:

uci show | grep submodel

will output:

system.@system[0].submodel='RM-2455v3-1L-X'
