BLE OTA with the STM32F401RE

Username123 · ‎2025-04-26

I am working on BLE OTA with the STM32F401RE. I am encountering an error, and I’m attaching a screenshot below. Please take a look and let me know what the issue might be.

"OTA" just means "Over The Air" - what are you trying to do over-the-air?

Do you mean OTA firmware update ?

You forgot the screenshot!

Probably also need to give details of what BLE you're using, how you're attempting to do the OTA, etc ...

How to write your question to maximize your chances to find a solution.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I think @Kumar123 and @Username123 need to decide who is going to start these questions, rather than duplicate them ...

I need help with BLE OTA (Over-The-Air) programming. I'm using an STM32F401RE board and the X-Nucleo-BNRG2A1 Bluetooth module. I'm trying to upload a .bin file using the ST BLE Sensor app through the Bluetooth module (X-Nucleo-BNRG2A1), but I keep encountering a transmission error. I've tried changing the sector address and adjusting the byte size, but I'm still getting the same issue. I'll attach images of the Bluetooth module and the app error for reference.
