Hi, I will connect multiple M5 Atomic, Paper and Core Controller with my Progressive Web App. This all should work offline. Otherwise I would use MQTT over internet.

OoT .. This is a little bit like "Offline Of Things".

The only solution right now is for me to make one controller acting as master, hosting an socket server and serving a wifi access point?

I have an Core2 and the COM.X NB IoT with an unlocked SIM card for a data connection. Now I would setup an wifi access point and for internet connectivity I would use the 3G connection.

How can I use this module in UI Flow to get the connection .. for example to connect to an mqtt broker like I would do when the Core2 is connected to wifi? And maybe all other connected wifi clients can directly communicate with the internet and.

I would love to see the BLE support written on the box useable in the software. That would be a really great feature because currently I connect to the phone via wifi and that's a disadvantageous way. My dream would be "PWA > BLE > Atom".

@felmue Super!!!

The EEPROM seem to have some problems with integer values and fast timing.

I store my integer now as string and wait until read is finished and it works.

@mchott I tried several things including EEPROM.

Is it possible that the EEPROM function on the Atom Matrix simply does not exist? The button B on the side does not exist in UIflow either.

Is there a way to save a variable value permanent. So after a power cycle I can use this value?

Currently I have to set the value in the UIflow and flash the AtomMatrix.
