Hi,
I'm trying to use Master Control Panel to communicate with a sensor that we've developped (nRF52 based). I have the nRF51 dongle (PCA10031).
When I start the application Master Control Panel I receive the message 'No master emulator found'. If I click on File and then 'Flash Programming...' I receive the error 'No device selected'.
A colleague has reprogrammed the dongle previously for another usage. I've tried to reprogram the dongle by dragging the file MEFW_nrf51822_0.11.0_firmware_1M.hex into the mounted USB drive 'MBED'. The drive then closes and reappears and the MEFW_nrf51822_0.11.0_firmware_1M.hex has disappeared. If I unplug the dongle and plug it back in LD1 turns white/light purple.
I still however cannot access the dongle from Master Control Panel, I still have the same mesage 'No master emulator found'.
Please help! Lee
