Adafruit Metro M4 Express AirLift (WiFi)

Post by crsthorn »

Greetings,

Is it possible to "upload" new programs to an Adafruit Metro M4 Express AirLift (WiFi) through the Arduino IDE program via WiFi - as opposed to being connected to the USB port with a physical cable?

Thanks for any insight,

Adafruit does not provide any utilities to update a sketch OTA (Over the Air) via WiFi or BLE as of now.

There are some third parties that are starting to do it such as Arduino IoT OTA.

https://www.arduino.cc/en/Tutorial/ota-getting-started

I've often needed this functionality and my solution has been to use a Pi Zero for network access and run the microcontroller off the Pi's USB port. Then use arduino-cli for remote access to update code and have a serial console to the microcontroller. In some ways this is a easier solution as the Pi is much more robust for network access and uploading code.

I too look forward to the day of ubiquitous OTA updates.
