@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).
Thanks

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.

Hi,
I have not been able to find it, but what is the maximum milli amperes this unit can provide ?

Anyone knows?
Thanks.

@felmue And indeed, I needed to add a delay before sending the payload. I had hoped that it would be necessary (in order to speed up he process of waking up, sending and going to sleep).

Dear all,
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";
int Payload_Length;
Payload_Length=payload.length();

SerialAT.println("AT+CMQTTTOPIC=0,"+String(Payload_Length)); // Input the publish message topic <client_index,req_length>
SerialAT.println(payload);
Read_Response_Ignore_OK(3000);

payload="field1=345&field2=543";
Serial.print(" ");
Payload_Length=payload.length();
Serial.println ("AT+CMQTTPAYLOAD=0,"+String(Payload_Length));
SerialAT.println("AT+CMQTTPAYLOAD=0,"+String(Payload_Length)); // input the publish message body <client_index,req_length>
SerialAT.println(payload);
//delay(50);
Read_Response_Ignore_OK(1000);

SerialAT.println("AT+CMQTTPUB=0,0,60,0,0"); // Publish a message to the server <client_id,qos,pub_timeout,retained>
Read_Response_Ignore_OK(1000);

@jeets +CSQ: 99,99 tells me that you don't have a signal.

@felmue Indeed, According to the manual Ready means MT is not pending for any password.

For those that need to connect their devices to a Eduroam network, this is a great link which helped me to get it working :

Many thanks to Martinus96!

Thanks,
Indeed,
This works :
display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height,0,0,JPEG_DIV_2);
