@felmue I just read this post. I am also facing high current during deep sleep om the M5Atom.
I am curious : could you give an example code how to power down (expect for AXP and RTC).

RE: Remote Sensing with Core2 (UIFlow) via LORA Point-to-point
Interesting question. M5Stack provides P2P LoRa example along with their documents. My suggestion is to make a proof of principle what you need. Then try the max achievable distance. Mqtt is another challenge but also many examples on GitHub.
SIM7600 and ThingSpeak, unable to publish
I nearly got SIM7600, MQTT and Thingspeak working. But I am not able to get the public working.
This is my basic syntax:
The module returns OK status, so so far so good. But no data shows up in my channel.
The weird things is I use the same Topic and message structure as with my SIM7080 module, and that works. Any suggestions?
My last part of the code :
String payload="channels/"+ String(ChannelId)+"/publish";
SerialAT.println("AT+CMQTTTOPIC=0,"+String(Payload_Length)); // Input the publish message topic <client_index,req_length>
SerialAT.println("AT+CMQTTPAYLOAD=0,"+String(Payload_Length)); // input the publish message body <client_index,req_length>
SerialAT.println("AT+CMQTTPUB=0,0,60,0,0"); // Publish a message to the server <client_id,qos,pub_timeout,retained>
