I have hearing aids which can be paired with devices to bring sound directly into my devices. I have only had them for about a month, but the Bluetooth has worked fine, until yesterday. Now, I can easily pair them with my iPhone, but not the iPad. When I try to the iPad simply says "not connected." I have tried re-booting the iPad, opening the battery doors on the devices and even replacing the batteries. I have also made sure the Bluetooth on my phone is not connected. Any suggestions.
