  @gleon said in UHF RFID on a M5Core2: Hi! I’ve been trying to compile the demo sketch for multiple reads. With some tweaking I was able to compile the demo single read sketch... But i have not been able to compile the multiple read. I've switched the library: #include <M5Core2.h> and also the ports for the serial comm: Serial2.begin(115200, SERIAL_8N1, 33, 32); But i could not make the multiple read sketch to compile. Actually, not sure if I'm having problems with this part of the code: RFID.Set_transmission_Power(2600); RFID.Set_the_Select_mode(); RFID.Delay(100); RFID.Readcallback(); RFID.clean_data(); or this one: cards = RFID.Multiple_polling_instructions(6); for (size_t i = 0; i < cards.len; i++) { if(cards.card[i]._EPC.length() == 24) { Serial.println("RSSI :" + cards.card[i]._RSSI); Serial.println("PC :" + cards.card[i]._PC); Serial.println("EPC :" + cards.card[i]._EPC); Serial.println("CRC :" + cards.card[i]._CRC); } } Serial.println(" "); RFID.clean_data(); Does anyone have aby thoughts on where to problem could be? Gleon, What Sketch do you use? You can't see EPC or Aton Lite or Core2 Thank s

  It seems that FastLED.h lack of some developper to get it working properly on ESP32 now. I jumped to AdaFruit NeoPixel lib and run this sketch successfully using your PIN values. #include <M5Core2.h> #include <Adafruit_NeoPixel.h> #define LEDBAR_PXL 10 #define LEDBAR_PIN 25 Adafruit_NeoPixel ledBar(LEDBAR_PXL, LEDBAR_PIN, NEO_GRB + NEO_KHZ800); void setup() { M5.begin(); // put your setup code here, to run once: ledBar.begin(); ledBar.show(); } void loop() { // put your main code here, to run repeatedly: ledBar.fill(0xFF0000); ledBar.show(); delay(750); ledBar.fill(0x000000); ledBar.show(); delay(500); }

  Hello @jorge5a the COM.GSM can only operate with 2G networks. Are you sure in your region 2G is still operational? The fact that the SIMs work in a smartphone doesn't automatically mean they work in the COM.GSM as the smartphone could connect using something else than 2G. That said you can try the following command. This will tell you if the modem has registered with a provider. AT+COPS? +COPS=0 // auto mode not registered +COPS=1 // manual mode not registered +COPS: 0,0,"CHINA MOBILE" // auto mode registered Or try to get a list of available providers. AT+COPS=? +COPS: (1,"Sunrise","Sunrise","22802",0),,(0,1,2,3,4),(0,1,2) Note: this command can take a long time and sometimes you need to issue it multiple times to get a result. Thanks Felix

  Thanks @teastain, @HWTaro9 but I'm especially looking for pcb footprint data like pad sizes and spacings to start with the pcb design.

  Thanks for the support! I've managed to 'fix' it. Reinstalled the IDF with predownloaded V4.0.3 version. I couldn't get the uint conversion working in the main.c. It came up with a lot of errors. So I decided to go for the quick and dirty solution; hardcoded sleep timer of four hours in microseconds. Not the way it supposed to be, but it works for me ;-)

  @felmue, it does not have the sticker, so I'm going to assume it's version 2 based on that.

  Felix, you were correct. All that was required was a cross-over of the white and yellow leads in the cable. Thanks. ...Brian

  @felmue You are right, it seems to be a voltage mismatch. The UART requests 5V, but ESP32 delivers only 3.3V. Reading: "On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI" Find more: https://manuals.plus/elechouse/pn532-nfc-rfid-module-manual#introduction Time to buy a M5stack reader unit and use the standard UiFlow drivers. Thanks!

  I think I probably have a defective unit. I have tried with only a single tab open, latest version of Google Chrome, tried it incognito mode also just to be sure some extension wasn't getting in the way. Despite all efforts it never connects to UIFlow. I know it's on the network because my router is showing it connected and sending/receiving some packets. I will probably stick with devices that have USB-C on them, this is way too much hassle and I don't want to have to rig up a programmer just to toy around with a prototyping device. Oh well, at least I'm only out $5.

  Hi Felix, thank you for your fast reply. I've used different Atmega, Attiny and STM32 based boards in the past, but new to ESP32. That's the reason for my "stupid" question. ;-) Thanks again.

  @srmobar said in Just a single M5Stack Plus-Module and no idea what to do: @ajb2k3 Thanks! Looking forward to additional tipps. My goal would be, to not require a core but to find a way to interact with it another way. If this is not possible, I concede :) I'm keen to try out different things and be it just for the sake of trying it. Can't be bad to learn a thing or two along the way While it’s designed for ‘Tara know, your not limited to M5Stack. You just need to understand the pin outs and communication method
