  Hey Dennis, sounds like you’ve covered most of the basics. A few things to check: make sure the antenna switch (INT/EXT) is physically set correctly on the module. Also, the NEO-M8N can take a few minutes for a cold start—try leaving it powered outside for 15–20 minutes. Lastly, ensure it has a clean 3.3V power source; voltage drops can affect satellite acquisition. If none of that helps, try updating the GPS firmware via u-center. Two dead modules is unlikely, but not impossible. Good luck!

  To create a server with SIM800L, use GPRS to get a dynamic IP from your carrier. Enable TCP listening with AT+CIPSERVER=1,80. Forward incoming data to your M5Stack via serial. Since the IP is dynamic, use a DDNS service or periodically send the IP via SMS/email. Alternatively, have the M5Stack poll a cloud server for commands. SIM800L has limited capabilities, so keep the website simple (raw HTTP requests). Check the SIM800L AT command manual for TCP/IP setup details.

  Thanks ChirpyChips aka @Beormund.

  I used your implementation with ESPHome to interface with a Schneider Phase Inverter. I wrote a tutorial on Hackster.io.

  Hello @teastain

  I am afraid I cannot help, sorry. I exclusively use Visual Studio Code with PlatformIO / pioarduino (which so far doesn't have this issue).

  Note: Visual Studio Code / PlatformIO doesn't use M5Stack boards and setting up new Cores (M5Stack and others) can sometimes be quite difficult as well.

  Thanks
  Felix

  Hi, I used the chat, but it didn’t help.

  I’m using a similar code with Pulse mode:

  AtomS3 Lite + QRCode2 Base = 230mA
  AtomS3 Lite + QRCode1.1 Base = 75mA

  That’s too big of a difference when using a battery.

  import os, sys, io import M5 from M5 import * import time from base import AtomicQRCode2Base base_qrcode2 = None def setup(): global base_qrcode2, data M5.begin() base_qrcode2 = AtomicQRCode2Base(2, 5, 6, 7) base_qrcode2.set_trigger_mode(base_qrcode2.TRIGGER_MODE_PULSE) base_qrcode2.set_trig(0) time.sleep_ms(30) base_qrcode2.set_trig(1) print('take measurements') def loop(): global base_qrcode2, data time.sleep_ms(30)

  @yuyun2000 Thank you for your response. I will try it out with Arduino as soon as possible.

  Just a quick question to make sure we're on the same page. We are talking about the integrated IMU in the AtomS3R, no external accelerometer, right?

  I will try to find more details in the documentation, but as far as I can see, the only place where the IMU is mentioned in the schematics is the IMU_INT that's connected to this XTAL_32K_N.

  I will update you as soon as I have news.
