HC-50 Bluetooth Module Not Discoverable For Pairing

The HC-50 is an extremely common Bluetooth module that can be set up with Arduino to connect to Android, Iphones and computers via Bluetooth to send and receive data.

I got mine from ebay: http://goo.gl/1qjxFN

I connected the module to my Arduino uno exactly like this YouTube tutorial : - YouTube

My modules LED is blinking and I can place it into AT command mode and send AT commands to it successfully finding out its version and changing its name like in this tutorial : Configuring The HC-05 Bluetooth Module with AT Commands - YouTube

However the module is 100% undiscoverable when trying to pair with it. I tried to pair using 2 different Android phones, Android tablet, Ipad and a computer. Nothing is finding it what's so ever.

This is extremely frustrating and I hope someone out there who has experience with this module can offer some help or advice?

Thanks in advance,
Jack.

The HC-05 does not work with iPhone, but I guess that isn'r your problem.

Check that the pin-row is kosher. A couple of users have had problems with solder bridges.

Thanks for your response.

I've looked at the notes and I've connected it to the Arduino correctly. This is proven by the fact I can send AT commands to it and get a response via the Arduino serial prompt.

The notes also say that the pairing has nothing to do with the connection to the Arduino. When the Bluetooth module has power it should be discoverable by say my Android device and I should be able to pair to it.

I can't discover it with any device, Could it be faulty?

You mentioned pin-row and kosher. What do you mean check the the pin-row is Kosher?

Yes. Flashing LED means power on and ready to connect. All Arduino is doing at that stage is providing the power.

If the LED is flashing and nothing can see it, then maybe it is faulty.

I was assuming your HC-05 is on a JY-MCU backboard or the like. The only faults I am aware of have been solder bridges between the pins. I imagine this is easily fixed. These devices popular and reliable.
