  Thank you for your message. I posted my program. I got an error in the same time several times in this program. So, I measured the sensor value every 5 seconds, but I extended it every 10 seconds. I don't know if that was good, but so far it hasn't stopped for 3days. Please let me know if there is anything else you know.

  Hello @stackyarou it looks like the limiting factor is the MTU which by default is set to 23 bytes. I've tried to set a higher MTU on both sides using BLEDevice::setMTU(40);, but it did not help. I read somewhere that 23 bytes is the maximum for BLE 4.2 so maybe that is the reason? Thanks Felix

  Hello @OfureAlakhume the M5Stack M-Bus is described here and the ECG Module seems to use GPIO13, GPIO5, 5 V and GND. Thanks Felix

  Danke @felmue , Your answer pointed me in the right direction. The voltage between GND and BAT pins was indeed 4.0V+, so I went back to check my code. I noticed that the official documentation for the AXP on the M5StickC only mentions M5.Axp.GetVbatData() (which is what I used and what gave me weird readings) but the AXP code example uses M5.Axp.GetBatVoltage() and the latter actually gives me the correct number. What's the difference between these two? Is it just the *1.1/1000? Cheers, Flo

  Sound like the battery protection circuit has tripped. Try pluging it into a none intelleegent USB charge for around 5 hours (with the charger switched on) and see if it come to life. If not, it could be that it has died and needs replacing.

  @m5stack I supplied 5v to Ⅿ5 BASIC, but it doesn't work. Why? I connected + 5.1v to the pin socket battery and connected -t o GND. Is it not possible to supply power from the pin socket?

  I ask M5stack support, here is their answer: "The 30-Pin connector we are using is a customized one. The pin height with 3mm is no problem to be compatible."
