I can not connect the Bluetooth HM-10 to the Arduino Uno

I tried everything, really, everything. The module HM-10(bluetooth) has its own LED and it blinks, than if you connect to it from your application, the LED stops blinking, and you get UUIDon iDevice.

The problem starts when you try to program the module from UARTand send "AT", to receive "OK", from the arduino serial monitor (on Mac).

So, I tried to connect it tx/rxvia a TTL converter to arduino uno and send commands from the monitor, it did not work.

than I tried to connect it directly and used this link: How to use BLE Shield based on the Bluetooth HM-10 module?

does not work (do not answer for "AT").

I also tried this: http://www.seeedstudio.com/wiki/Bluetooth_V4.0_HM-11_BLE_Module

and this: http://www.instructables.com/id/Control-RGB-lights-from-Android-with-Arduino-Bluet/step1/Assemble-test-configure-your-Bluetooth-LE-module/

Without an answer .i we will not receive a response from the module (the rx module switches to tx on the arduino)

I really don’t know what the deal was with this module, it may have broken it (if so, how can I connect to it from my iPad and get its UUID?).

Is there anything else I can do? Is there an option that I put in some mode that can no longer respond?

Mine requires "Both NL and CR" in the Arduino SerialMonitors settings if I enter the manuall commands and also <mySerial>.println("AT");instead <mySerial>.print("AT");!
