      I do not think you have a defective unit. The thing is that uiflow is kept running in loops and when you try to flash with estool, or connect with rshell that unit does it in pauses. The same thing happens if you connect to a StickC (uiflow loaded) with rshell. If you flash a generic Micropython and then try to flash again with esptool this should not happen as Micropython with out running any heavy app is not interrupting.

      Hi @felmue Thanks, using your link, I mange to find an untestet example using the library here https://www.hackster.io/tommyho/arduino-web-radio-player-c4cb23 but first when I added code to enable the I2S Speaker (using code from the example 'speak.ino' I manage to get something out of the speaker on CORE2, but the quality make it useless - it might get better turning the code, so will try do some test on that.

      Unfortunately the GOPLUS 2 is not specific to CORE2 it is also the same problem with the FACE2 which is not compatible with the CORE 2 ... It is a big marketing error of M5STACK. For a better connection I added small pieces of schotch under the PCB at the level of the screws on the GOPLUS 2.

      Hello @wa-berlin you can't. Functions w/o numTimer argument will return the internal number assigned to a specific timer. You don't have direct control about which timer gets which number, but you can keep a record of the number assigned to a given timer to further manipulate it. Below is an example with 2 timers (A and B). Timer A counts up ever 2 seconds, whereas timer B counts up every second and stops at 10. With button A you can enable and disable timer A. With button B you can restart timer B once it has stopped. #include <M5Core2.h> #include <utility/M5Timer.h> M5Timer M5T; int mytimerA = -1; int mytimerB = -1; int mycountA = 0; int mycountB = 0; void myTimerACB(void) { mycountA++; } void myTimerBCB(void) { mycountB++; } void setup() { M5.begin(); M5.Lcd.setTextSize(3); mytimerA = M5T.setInterval(2000, myTimerACB); mytimerB = M5T.setTimer(1000, myTimerBCB, 10); } void loop() { M5.update(); M5T.run(); if(M5.BtnA.wasPressed() == true) { if(M5T.isEnabled(mytimerA) == true) { M5T.disable(mytimerA); } else { M5T.enable(mytimerA); } } if(M5.BtnB.wasPressed() == true) { if(M5T.isEnabled(mytimerB) == false) { M5T.deleteTimer(mytimerB); mycountB = 0; mytimerB = M5T.setTimer(1000, myTimerBCB, 10); } } M5.Lcd.setCursor(0, 0); M5.Lcd.printf("Timer A: %s\n", M5T.isEnabled(mytimerA) ? "enabled " : "disabled"); M5.Lcd.printf("Timer A: %04d", mycountA); M5.Lcd.setCursor(0, 100); M5.Lcd.printf("Timer B: %s\n", M5T.isEnabled(mytimerB) ? "enabled " : "disabled"); M5.Lcd.printf("Timer B: %04d", mycountB); } Good luck! Felix

      It is definitely something to do with the size of the program. Once it reaches a certain size it will no longer run. All I have to do is delete anything (reducing the size) and it will run again. I provided a sample of my code to tech support and they are working with engineering to investigate.
