I assume that I a am not the first one to ask, but how can I select other fonts? Thanks

I have been googling around, no understandable answers found. But I am sure I am not the only one with this interest.
Could anyone explain the binary format of the sound stream used in the echo? And also nice to have : howto proces a mp3 or wav file into the required binary array to be used in the Echo?
Thanks.

A few tips who want to start with this module:
1] Remove PIN code, makes life much easier
2] Download the application notes for this module. Both the complete AT instruction set and the note on HTTP application. This document provides clear instructions how to use HTTP, GET, POST etc
3] I experienced ERROR response on SHCONF command. Googled around, saw numerous hits. It appears that switching off and on power does the trick for me. I did not see a reset AT instruction
4] I got it all working with these instructions :
Serial.println("Begin..");
//pinMode(RXD2, INPUT);
//pinMode(TXD2, OUTPUT);
//showLog("Reset Module...");
//SIM7020
//DTU.Init(&Serial1,36, 26);
//Serial1.begin(115200, SERIAL_8N1, RXD2, TXD2);

@paulpattyn Uh, how about use Google : https://www.instructables.com/Post-to-Google-Docs-with-Arduino/
Regards

@cepics said in ATOM Lite Display not display in smallHd 503:

SmallHD503 datasheet

I read that you are also struggling with this (5 inch?) display. I am facing the same issues with Waveshare 5inch display. Although I have the very strong feeling that the software on the M5AtomDisplay as shipped is different from the GitHub factory test. Have you been able to get things working?

#include <HardwareSerial.h>
HardwareSerial Comm(1);

Comm.begin(115200, SERIAL_8N1,TX_pin,RX_pin); // TX RX

Comm.print("AT+IPR=115200\r"); // Set text mode

Last command should return an OK. If not, it could be that you have mixed up TX and RX pins or a power issue.

To read the reply from the module you could use something like this :
while (millis()<wait_until)
{
while (Comm.available())
{
ccc=Comm.read();
//Serial.print(ccc);
if (k<buffer_size-1)
{
Receive_buffer[k]=ccc;
k++;
}
}
Receive_buffer[k]=NULL;
if (strstr(Receive_buffer,StopCharArray)!=NULL)
{
//Serial.println("OK found");
// SIM7600_Error=0;
Receive_buffer[k]=NULL;
return false;
}
}

Okay, Had a lot of <bad language> getting sending email working.
Than I realized that powering the module straight from the M5StickC appeared to causes glitches. I have placed a capacitor on top of the 5Volt to the module and now I am able to send emails also. For those that are interested, here is the code (with a lot of overhead no doubt, that works for me ):

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.

Solved
I don't why I have been klinging on to Serial2, it got me in all kind of testing out, but the solution is to use Serial 1.

@laursena please check the version of ClosedCube.cpp and ClosedCube.h you are using. The one that is provided by M5stack is the newest.
(* In the examples of M5StickCPlus in the directory Unit/PaHub you may find these documents. *)
