Over the Air (OTA) Device Firmware Updates (DFU)

Hi

Is there an example where I can use flutter_blue to perform OTA firmware updates to a device?

[jthansen]

This is working for me on Android but I am having some difficulty with iOS. I believe it has to do with how iOS creates a UUID instead of using the MAC address like Android. Any ideas on how to fix that? https://github.com/fengqiangboy/flutter-nordic-dfu

Who has experience using the Cypress BLE chipset or BLE module? https://www.cypress.com/part/cyble-214015-01

I am the same question

You can send the update firmware file in multiple parts, in my case my file has 740k bytes. I divided into multiples parts of 448 bytes (payload) + protocol packets. You need to configure MTU mine is 500) and for > Android 8 devices, you need the Connection Priority. This OTA process in the best conditions, take me 3 minutes max.
