I have several nodes, four of them on one local mesh and two of them on another mesh out of LoRa range. All nodes share a private channel in slot 1. I have the public channel configured as secondary in slot 0 and the private channels configured as primary. MQTT is enabled on the private channel. WiFi is good on both ends.
Everything works as expected, except there is no MQTT communication between the two meshes. Locally, everything is fine. If I enable MQTT on the public channel I see the usual flood of MQTT nodes.
I am on firmware 2.3.3.8187fa7 if it matters.
Any ideas?
