@EricB if you are on Facebook you can find a free sample of my books as well as some write up on hackster.io

Hello @gordsh

it looks like this warning/error has been fixed a while ago - see here.

Thanks
Felix

@EricB I'm going to have to Ask this but Did you read the instructions?
I know I didn't and missed the command!

In the root folder run :

./user/local/m5stack/resize_mmc.sh

Hi @riztronic
We have fully tested the Arduino code running normally and without a problem!
You can get the newest code here:
https://github.com/m5stack/M5-LoRa-E220/blob/main/examples/P2P_TX_RX/P2P_TX_RX.ino
The test video is here:

The problem may be that your TX/RX pins are reversed

@pitiaa
哪款产品？

@kaidencoolkid Untill you know how the StickCplus2 works or communicates, only install UIFLow2

@kaidencoolkid Stupid autouncorrect that should have said "my" no "the"!
Yes on my channel.

@Kabron you highlighted m5stampC3 and m5Stack arduino libraries which are two different classes of esp32
C3 use on die usb adapters, others use external usb adapters

@brrainz @erickadengler you could just try removing the connector and solder wire between each unit or now that you have a prototype made with units, look up the circuit diagrams on the site and build a custom pcb containing the devices.

Another route is to learn how to make a custom cable/connector.
BTW the connectors on the devices are male and not female and so adapters must be female not male
