Hopefully a straightforward question.
Say wanted to use a ‘mobile’ Heltec V3 device to forward Meshtastic packets to a MQTT server.
It would be near a smartphone with functional data connection.
Would setup the Heltec device to do the actual forwarding, using the MQTT Module? The smartphone would have to provide a WiFi Hotspot.
Rather than the Android App (connected over Serial or BT) doing the connection to the MQTT server. The smartphone is already connected, because it’s providing the power over USB OTG.
Dont find any options to configure MQTT in the app itself.
Thanks
You can use either option; all supported Heltec devices use the ESP32 and support Wi-FI over 2.4 GHz. If you prefer to use Wi-Fi Hotspot tethering, you’d configure the Heltec to connect to your Wi-Fi Hotspot SSID, enable the MQTT upstream/downstream options in the MQTT Module, and enable your phone’s Hotspot feature.
I havent been able to find the option to enable MQTT forwarding within the app, just via the MQTT Module within ‘Module Configuration’ which is a meshtastic device option.
So looks like going with using Wifi between device and the phone. (was hoping to avoid that mainly for battery life) - can still use serial between the device and phone, as bluetooth wont be available.
