Hi there,
I am trying to go through the process of FW upgrade via FUOTA.
And I did follow this tutorial with go example and seems the process stucked cause multicast setup request did not get response.
I found that multicast group setup message was discard by my device’s FW, and I think the reason is the item “payload is encrypted” was No.
If I manually send a downlink and not to enable “is encrypted”(without frame-count), it will discard by my device’s FW since it cannot get frame-count.
I am wondering if anything I missed to setup a FUOTA campaign or just the FW’s bug.
Thanks~
Vic
