Deepsleep and LoRa Adaptative Data Rate (ADR)

[Pierre JUHEN]

Hi,

I started a prototype on Lopy4 using sleep, using ADR, and everything went smoothly.

When I modified the code, the lost packet increased a lot, and I found out that evey packet was sent with a default DR_5 datarate.

For me, it means that the datarate is not saved / restored by nvram_save() and nvram_restore(), and therefore, you have to manage it. It's a pity, because if you want to rollout a battery base prototype, you can have conservative policy (and consume energy) or accept to loose packet, or even have devices that can't join. Or tune it manually by sending messages to the devices.

Am I right ?

Regards,

Pierre

@Pierre-JUHEN can you let us know which version of the firmware you are using?

I vaguely remember something about this issue a long while ago, but I don’t remember if that was fixed or not, and if so, in which version.
