Gents, I am experiencing a strange issue with RAK11200 when trying to configure Meshtastic MQTT module. I am connected to the node via WiFi, configuring the node using Android phone. I managed to enable MQTT, but then when I try to configure it I input all the data, click SEND, I get “Delivery confirmed” message, but when I leave MQTT configuration screen and bring it back again, the settings are not updated. After many many attempts I eventually managed to configure all settings apart from enabling TLS. No matter what I do that switch always come back to “disabled” position. I also tried to configure it via USB using web client, but to no avail. Firmware updated to latest stable version. Any ideas what may be the reason?
As far as I know Meshtastic firmware on the RAK11200 does not support TLS.
Better you ask Meshtastic about it.
