Well, helps to get the correct ver of the software first. But, there is no pin. So long as it can be seen (can do a BT scan on phone or tablet to verify its visable) the client software will find and connect to it. However, it's not the most stable platform. Found myself having to re-enter settings multiple times because it was "failing" while uploading new settings. Overall it's a decent product just needs work. Can update more latter as I use it.
