  @dukenukke M5Stack library contains an error in LoRaWan.cpp the definition of first element of array: const char *physTypeStr[10] = {"EU434", "EU868".... should be like this: const char *physTypeStr[10] = {"EU433", "EU868".... Since module RHF76 doesn't understand command like AT+DR=EU434

  It is safe, but the battery will charge each other.

  I followed up on this project with another that's a real calculator. It was more work than I had anticipated; that might explain why there are so few examples: https://github.com/vkichline/FullCalculator-Arduino The README includes pictures this time.

  RS232 to M5 Basic/Gray?

  Hello John A couple of M5Stack modules (like GPS) already use a serial connection via GPIO16 and GPIO17. However GPIOs only provide logical voltage levels (0V / +3.3V). Assuming your source is a standard RS232 device the voltage levels can go down to -15V and up to +15V so you probably need a level converter like this one: https://www.amazon.com/Serial-Converter-Equipment-Upgrades-Doupont/dp/B01N42QW8X/ref=sr_1_6?crid=2OZ5U3Q7GY5OS&dchild=1&keywords=ttl+rs232+converter&qid=1597992249&sprefix=ttl+rs2%2Caps%2C276&sr=8-6 Cheers Felix

  Hello again I think the following library should allow you to switch between WiFi or Ethernet OTA: https://github.com/espressif/arduino-esp32/tree/master/libraries/Update Use it with either a WiFiClient or EthernetClient client. Cheers Felix

  @m5stack Hello! I would like to know to which bronchi pins A and B of the RS485 extension card are connected to the BUS, please. I can't get my M5 to communicate via RS485, however I soldered the small expansion card well. For my program I am using an ESP32 based Arduino library for the Modbus RTU

  Hi @fblais which demo web server did you try? I am able to run below web server code successfully on my M5Stack Grey with LAN module attached. M5Stack/examples/Modules/LAN_W5500/WebServer/WebServer.ino Note: I had to adjust the IP address to match my local network. Maybe that is your issue as well? Good luck Felix

  ATOM RS-485 Kit - bad Rx performance?

  R

  So, after many experiments I'm sorry to report that the RS-485 Atom module has very bad Rx characteristics. The issue of getting corrupted data was related to problems in the serial support of the arduino-esp32 project. After moving to git version I still had several problems: missing bytes zero byte at end of rx block last byte of block was sometimes corrupted I've then tried replacing the RS-485 Hat with another RS485-to-RS422 adapter and since then it works flawlessly. Something in the electrical design of the RS-485 hat must be messing up the Rx data.
