[nRF51822] It is difficult to pair nRFready keyboard with 2.4G dongle.

[Jeffery]

Keyboard source: Desktop 2 v1.0.5 Dongle source: 1. Desktop 2 v1.0.5 dongle hex; 2. Desktop 1.2.2.293 dongle hex

I found it is very defficult to pair the keyboard with 2.4G dongle. Press pairing button thousand times. Also, Try power off and then on thousand times. Then, FINALLY it can work on Desktop 2 v1.0.5 dongle. But, never succeed on Desktop 1.2.2.293 dongle. Instead, it's very easy to connect this keyboard to BTLE. Did you realize this problem? Thanks.

Hi Jeffery, I'm not sure exactly what causes the problem, so it's difficult to say if this is what you're seeing. But it's worth a shot to try using a different USB port or rebooting the PC. At least you can eliminate one potential cause..

This issue is particularly easy to notice when actively developing on the dongle: unplugging->programing->replugging a lot. I ended up deleting relevant windows registry entries each time I unplugged the dongle to always trigger the driver install (the one you see running in the taskbar when plugging in a new device).
