Hi all,
I asked this question before but I am not able up to now to find solution. How to use DFU example of SDK 7.1 for the S130 SoftDevice. I have tried some flash address...
I am currently developing a bootloader for N548 chip from Dynastream/Nordic.
I am following the project example for the S310 soft device and using IAR.
The project had been...
So I see ble_app_hrs and others have some nice examples of buttonless reboot into DFU bootloader. But for security reasons, I'd rather the user hold down the reset button...
