OTA Bootloader Example for MCXW71

[VeridianJack]

Reading through the Bluetooth® Low Energy Application Developer’s Guide.

There should be an example project that implements OTA BLE through a bootloader.

The OTAP Bootloader project and source code can be found in the \boards\<board>\wireless_examples\framework\bootloader_otap\ folder.

Does this example exist for the MCXW71 / KW45 chips?

Which SDK would have this example that could be most easily ported?

Hello

To use the OTAP Bootloader I would recommend using the KW45B41Z-EVK SDK Most Recent Version (25.03.00), the example you'll need to implement is the [otap_client_att_freertos]

I would recommend checking the Bluetooth Low Energy Demo Applications User’s Guide Chapter 5.11 for further information about OTAP in KW45. Bluetooth Low Energy Demo Applications User’s Guide

Also, This Application note can be useful regarding the KW45 OTAP bootloader Creating Firmware Update Image for KW45B41Z/K32W148 using Over the Air Programming Tool
