manually set join request datarate

[alejandro ballesta]

Hi team,

is it possible to set manually join datarate before actually joining?
I tried setting TXDR before but JOIN does not match the datarate selected.
The idea behind this is to try joining first at SF7, if not successfull next time will try at SF12.

Firmware : 3.1.0-mbed161
Library : 3.1.0-mbed161
MTS-Lora : 3.1.0

Thanks

AT Firmware does not have a setting to allow this.

Using the library it is possible to disable datarate hopping for joins.

dot->GetSettings().Test.DisableRandomJoinDatarate = lora::ON;

Hi Jason,
re-reading your answer I suppose there is no ‘command way’ to change this setting to lora::ON, right?
Do you think maybe we can lower the power output for the first join? The problem we want to avoid is concurrents “join requests” due to all nodes powering up at the same time.
We are also applying some random delay to the first join to prevent interferences.
Thanks!

Power can be reduced.
