I have implmented OTA DFU in my project with SDK 6.1 and SD 7. And it works perfect with MCP in android.
But it also has to work with iOS. But it doesn't. The sequence is as follows. The device is showing up as dfutarg, even though the program is still in the application. However, if I try to upload the new firmware it says wait.. And then after a few seconds it says, DFU connection has been lost. At this point the device is starting in the bootloader, but nothing happens. Even though if I try again.
It also works with nRF toolbox for android. Anyone who has problems like this?
