Possible OTA options.

[Balamurugan]

Hi,

We bought smart watch from company xyz. Watch is running using Nrf52840 and supports buttonless DFU. we are customizing the smart watch firmware as per our requirements with xyz company support. Firmware is developed with support of dev kit and development is over, we need load into actual watch to test.

Right now watch is running with xyz company firmware and its assembled watch so jlink pin is not accessible. Now we want to load our firmware into smart watch trough OTA as it supports DFU.

As per our understanding to do OTA update over xyz company firmware possible options are:

1. Get private key from xyz company and create a OTA file(our application Hex + Key)
2. Share our application hex to xyz company and let them create OTA files for us and share it.

Apart from above options is there any other way to OTA update the smart watch with our firmware.

Thanks,

Bala
