Android BLE OTA Firmware Update

[ChNi_2249236]

Hey Guys and Gals,

   

Whenever I send a firmware update the file is sent successfully but the firmware is identical to the previous iteration. In short the changes I've made to the firmware aren't shown even after the OTA firmware update. Is there anything else I have to do??

   

Thanks In Advance!

It depends on the OTA bootloader you have on your device: There are a couple types of bootloader: External memory, fixed stack, upgradeable stack, etc. Each one has limitations with pros/cons involved.

There was a problem when writing to the SD Card the file was overwriting itself each time data was sent. Everything is up and running now, thank you!
