Hello,
We have a dev project where one of the components is a device running on the nRF52DK, with NRF52382. The component is basically a UART to BLE interface, based on example code from Nordic. This component has been stable for a long time with no changes. We use it to configure ourt real target over BLE.
Recently we programmed a new instance of this board and the device failed. What is really strange is that when we reprogrammed a working device with our stable .hex file, the device stopped working - even though we downloaded the FLASH of the device and did a diff with our styable .hex and found that they are identical, to the last byte!
When we investigate the issue, it seems that the device is able to connect to the target over BLE but as soon as any data is sent, the connection drops, for some reason.
What is really odd is that re-programming the SAME board with the SAME firmware causes it to stop working.
Now we are wondering if there could be something with either
1. device settings, fuses etc (we couldn't find any settings that are not in the .hex file though)
2. recent changes and updates to the nrfjprog
Any ideas? Can we download and try older versions of nrjjprog somewhere to try?
thank you in advance.
