Very nice.

Hello @pop-k I am glad to hear that. Thank you for reporting back. @m5stack : please check this pull-request. Thank you. Thanks Felix

Hello @fly4fun thank you and thank you for reporting back. I am glad you got it working. @m5stack: Please check out this pull-request. Thank you. Most of those functions return true if successful (and false otherwise). Thanks Felix

@german-figueroa2000 What you did was to run the code on the core2 in test mode. You need to download the code to the core 2 from which it will be run on boot. There are some differences between running in test mode and running in app mode and the biggest is that in app mode you may need to add blocks to initialise wifi communications where as in test mode, the wifi is auto magically run for us.

Thanks Teastain I have the expansion module for CORE 2 I am looking for advice on the mode of communication to use to transfer from CORE2 to the ATOM Display, and how to transmit around 20 digital variables?

yes that's right I have given up hope

@felmue, thanks, also for the ```-tip!! After years of programming the ESP32 it takes a lot of time to get familair with the Core2 specifics

@mchott ESP_NOW in peer to peer mode. I wrote this simple bare-bones application to share with other makers. https://github.com/teastainGit/ESP_NOWpeer2peer I have a Core Basic communicating with two M5Stamps in the same room, controlling space heaters and an HVAC vent damper position. etc. The github example is used in all three devices

Hello @mchott in UIFlow 1.10.x have you tried the MQTT blocks under Modules - COM.X - NB-IoT? Thanks Felix

Hello @xha1e PoESP32 is a unit and meant to be controlled via Groove serial connection using AT commands. May I ask what is the reason you'd like to modify the preinstalled AT firmware? That said, if you look at the schematic you'll see J2 (Download Socket) in the bottom right corner. J2 can be used with an USB serial adapter to modify the preinstalled AT firmware. Note: J2 is internal and not populated. Note: the preinstalled internal firmware can be altered / replaced using Arduino IDE. But please be aware that restoring the preinstalled AT firmware requires the ESP-IDF build environment (which is different from the Arduino IDE). Preinstalled AT firmware source code and build instructions can be found here. Thanks Felix
