Hi simsas18:
I also have a HM10 BLE 6pins clone which may be seen by BLE smartphone applications but does not respond to AT cmd:
Question: how do you connected the CC2541 pins to Arduino?
I tried like that: GND<->GND , Tx<->Rx, Rx<->Tx and Bluetooth module Vcc to arduino 3.3v as well as 5v and not work
What it is wrong?
