How to activate Bootloader? (Nano 33 BLE - for OTA app)

[gbucas]

Hi guys,

Is there a way to activate the bootloader from code in sketch on the nano 33 BLE?

I want to add an OTA software update function to my iOS App (that already communicates well with the nano 33 BLE). Are there any examples/tips to help me to develop this (OTA) further?

BTW: Thanks for the new StringCharacteristic - makes it easy to emulate the Nordic UART Characteristic (and do many other useful things!).

Thanks!

Gerard

Closing.

Hello, I'm attempting to do the same. Did you find a nice resource? So far I'm going to purchase a J-Link and put a new bootloader on the nano 33 BLE via the SWD interface. Then attempt to program the nano with Nordic's software suit.

Thank you!

Still looking for an OTA solution for nano BLE 33 (using Bluetooth).

Has anyone managed to do this?

thanks

I’m also still looking, I have begun learning Zephyr as it has FOTA capabilities. But I’m not sure if I have to change the boot loader yet (still learning).
But learning an entire RTOS and build system, seems like a lot just to get over the air updates.
