Lorawan OTA multicast problem

[gouttedencre]

What are the steps to reproduce this issue?

1. update the firmware to development 1.20.0.rc13
2. install LoraServer 3.2.1
3. run the Lorawan OTA example

What happens?

Everything works fine until the firmware update is pushed down to the LoPy4 in multicast. In the logs of the gateway the packets are shown but are never received by the LoPy4.

What were you expecting to happen?

The LoPy4 to receive the multicast packets

Any logs, error output, etc?

Just the watchdog who triggers as no packets are received

Any other comments?

The lorawan multicast function doesn't seem to exist in the stable release of the firmware (1.18.2.r7). I also wanted to try to manually create a multicast session but I can't find any API.

What versions of software are you using?

• LoPy4 with board v2.1A,
