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);

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

@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?

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 ):

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;

{
//Serial.println("OK found");
// SIM7600_Error=0;
Receive_buffer[k]=NULL;
return false;
}
}

Wow,
I have uploaded the standard M5Unified Button code to my M5Core2.
I know the program is running because my serial.print shows button counts.
But the display shows nothing.
I have tried this on multiple Core2 of which I know the display is not defect. All boards and libs are updated (as fwr as i know).
What am i doing wrong here?
Thanks

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.

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.

These are the libs that I am using. Could it be that somehow there is a difference with your config?

@felmue Thank you. I tried this extra spi call because I assumed that something is wrong with SPI. Leaving out this call does not solve the problem either. Bot M5Unified and and radiolib are updated. M5Stack board manager is also updated. This is very weird. Not sure how to process further.

I receive this debug error message : GPIO pre-transfer timeout, is it connected? which is located in in the function
int16_t Module::SPItransferStream(const uint8_t* cmd, uint8_t cmdLen, bool write, const uint8_t* dataOut, uint8_t* dataIn, size_t numBytes, bool waitForGpio)
in the file Module.cpp

I am using the example in this M5Stack link : https://docs.m5stack.com/en/arduino/unit_c6l/lora

Help is appreciated.
Regards

Hi, I am using the following program to test Lora on this model. However, i receive this error: [SX1262] Initializing... Failed, code: -2. I assume that i am using the correct ports as given in rthe documentation. Any suggestions ? Thanks ```

Solved: somehow commented the lv_tick_inc(5); in the main loop.

@felmue thanks. Indeed. Leaving out m5unified does the trick. Though I haven’t read anything about an incompatibility between M5Unified and FastLed. Regards.

Hi am stumped,
I just can't control the leds anymore.
This is my code, no led goes on.
Any suggestion where I am going terrible wrong?

#include <arduino.h>
 #include <M5Unified.h>
 #include <FastLED.h>
 #define NUM_LEDS 25
#define DATA_PIN 27
#define CLOCK_PIN 13
CRGB leds[NUM_LEDS];

void setup() {
auto cfg = M5.config();
cfg.serial_baudrate = 115200;
cfg.output_power = true;
M5.begin(cfg);
    //FastLED.addLeds<WS2812, DATA_PIN,GRB>(leds, NUM_LEDS);  // GRB ordering is assumed
    FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS); 

    for (int i=0;i<NUM_LEDS;i++) {leds[i]=CRGB::Red;};FastLED.show();


}

@easytarget thank you. That is indeed an option. In my experience not to much work to get a Lora module working. We have a number of them in the field. But we would like the tab5 not become thicker as it is. We are now considering to place an Heltec Lora inside. Maybe that could work. Regards.

@felmue Thank you, that makes sense. Btw, a great product.

It appears that the tab5 is prepared to work with Lora. Any idea how?
Thanks
