Hi Kazola,
I have turned on two "CC2540_Keyfob" board in parallel trying to communicate with "HTC 1V" which supports "BT 4.0" protocol. When scanning for the devices from my mobile phone both of the devices are not detected. I see no LED's are blinking while presses the button on the keyfob. I dont have any USB dongle to use as BLE master to test the communication now. Is the indicator LED's will only start blinking after it get paired with another BT4.0 device?. Or what could be the response on the keyfob if it not get paired with right device.
Regards
