BT2S-M pairing issue

Hi,

I recently purchased a BT2S-M unit, and following the instruction given have connected it to an Arduino Uno board. I have triple-checked that the four necessary pins are properly connected to the Arduino, and that the device blinks to indicate that it is ready to pair, but neither my phone nor my laptop can successfully scan for the device in order to pair with it (though they can successfullt scan for and pair with each other).

I am not trained in this field so I am unable to diagnose the issue. I have power-cycled the unit several times with no improvement.

Could you please advise a course of action, if there is any short of swapping it for another unit?

Thanks,
Chris

Chris,

The BT2S-M is a master only device. Your computer and phone are also master devices, which means that they are all scanning for a device in pairing mode. I am sorry for any confusion, but I tried to keep it as clear as possible in the product profile.

The way the BT2S-M works is it constantly seeks, and attempts to pair with any BT2S-Slave device that has the same pin as itself. I have been told there is a way to put your phone into slave mode, but to be perfectly honest I haven’t been able to figure out if it is true or not.

Would you mind letting me know how I could have made it more clear in the product description? If you intended to use the device as a Slave just let me know, and I can help you through the return process. I will be more than happy to exchange them for you.

Respectfully,
Joseph Dattilo
