I’m trying to do app which read some sensor data from bluetooth signal coming from HC-05 bluetooth module which is controlled by arduino device.
But I got stuck right at the start. My Xperia 10 II did not pair with HC-05. It did find the device and when trying to connect, it will first ask password and then it shows ~2 second like connection was made, but then it disconnect and say nothing. Although it shows HC-05 in the list of paired devises. When trying to connect again it says something like “can not connect, make sure device is on…”. When I put HC-05 on AT command mode, it shows like there has never been connection between these two devices (which is probably true).
I tested and with android device there is no problem to pair it with HC-05, so module it self should be ok, right?
I’m not professional developer, more like beginner. And I have no idea where the problem is or how to start fix it. So if you can help me, please do it that simple I can understand.
I maybe should mention that pairing Xperia with my computer works as it should. So at the moment problem is only with HC-05.
