I cannot agree more with this need, to update firmware OTA. Having to dislodge any project or product that is already on and running, to locally connect it, simply to update firmware to fix a problem, is a cumbersome step that contradicts the intentions of the IoT. Firmware over the air (“FOTA”) is no doubt becoming more common and this post by Martin Harizanov should inspire you if you require a FOTA solution.
With the IoT booming nowadays, the number of connected devices grows exponentially and so does the related software that drives them. There is no doubt that Firmware Over The Air (FOTA) is a highly desirable – if not required – feature for any embedded project/product both DIY or commercial. Being able to provide a remote firmware update is obviously very beneficial. The opportunity here is to enhance product functionality, operational features and provide fixes for particular issues. Updating the firmware OTA may eliminate the need to bring a product into a service center for a repair. Although not every issue can be resolved with a firmware update, if one is available for a particular issue, it can save a lot of time and money.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Yeah I completely agree – it’s hard but doesn’t have to be big – the kernel, including networking and SUOTA, for my (as yet undeployed) Burning Man mesh project fits in 8k – software deployment is done with a simple “make push” that updates one unit, units in the mesh update each other
The unit-to-unit push is also smart; hive mind in full effect, love it!
