Hi Everyone
I'm developing a project using NRF52840 , the application needs OTA over BLE . It was working before without no issue , we tested in many devices and many times . However Today I try to use Device Manager to update the APP using the OTA , but this time it reports Invalid Image . I couldn't find any information about what could be the cause .
To make it works I had to enter in advance mode :
1. Read and Erase app
2. Upload the binary to App 0
3. Read again and Confirm
Why do I need to do this when Image is Invalid ?
and What is the reason that is invalid
Thanks in advance , below you can find the error and with nrf logs , mor details
