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

I do as you said and then follow: 1、mergehex.exe -m s110_nrf51822_5.2.1_softdevice.hex bootloader.hex -o app_ota.hex 2、Program app_ota.hex by using nrfjprog 3、Program app_ota.hex by using nrfjprog This can be done successfully.I wonder whether I can use the mergehex.exe to mergehex the three files(softdevice\ bootloader\application) as one file so that I just need to program only once?

Could you have any other good idear for make products and improve the efficiency.Thanks.

Look forward to your reply.Thanks
