Device is always in bootloader mode

[balaji]

Hi,

My device is always in bootloader mode, even if i flash the sample heart rate application it is not entering into the application. Actually, before it was working fine, i know that, if there is no valid application in the code region 1 the device should always in dfu mode, but after flashing a valid application like ble_app_hrs and ble_app_proximity, the device should enter into the application. I also checked this with the same device before, it was working fine, but now it is not working, So can anyone guess the source of the problem.

Regards, Balaji

Hi Balaji

I also faced the same issue while using command prompt for device firmware update. So I downloaded latest master control panel with API for DFU so that you can easily update the firmware.
