Hi
Install mqtt in the pi
https://www.instructables.com/id/Installing-MQTT-BrokerMosquitto-on-Raspberry-Pi/
Setup a Python app with a mqtt client on the pi
http://www.steves-internet-guide.com/into-mqtt-python-client/
Setup mqtt client on your M5Stick
https://github.com/m5stack/M5Cloud/tree/master/examples/MQTT
This should be a good start to get mqtt connected on the both devices.
Hi
Just add
HardwareSerial Serial2(2);
under #include <Arduino.h> in /Users/matthias/Documents/Arduino/libraries/M5Stack/src/LoRaWan.h
@watson Thanks for the reply
so I don't have to Street about the setup
Serial2.begin(9600, SERIAL_8N1, 16, 17);
Just use Uart and send command, Thanks with play around with it.
Hi
How can I send the following AT Command with UIFlow.
Serial2.begin(9600, SERIAL_8N1, 16, 17);
Serial2.flush();
Serial2.println("AT+RESET");
Do I have to use the Uart mod?
Thanks.
Hi
I managed to get connected with the following.
Thanks

Hi
Is there a example to connect a M5stack to the TTN network?
https://m5stack.github.io/m5-docs/#/en/product_documents/modules/module_lorawan
Thanks.
Hi
Is there any update on the new 868 and 915 modules.
Just waiting for them.... :P
