[Arduino] Problem connection Bluetooth

Hi all,

A while ago I got a HC06 bluetooth module. In the beginning everything worked OK, but now some problems have appeared. Pairing in Android works fine, as well as with my laptop. The problem arises when connecting my phone (Google Android 4.2 with Bluetooth 2.0 + EDR) to the device. BlueTooth Serial Controller 16 seems the only working app, but I would like to use my own application, based on the code described here https://www.instructables.com/id/Android-Bluetooth-Control-LED-Part-2/step8/Download/ Also other apps like BlueSerial Beta and Bluetooth ssp pro do not work. Does anyone have a clue how to solve this problem?

Many thanks in advance.

Hi, You're facing some problems with the code, right? I developed the tutorial based on my apk unWired (https://play.google.com/store/apps/details?id=com.pro.unwired&hl=pt_BR) Download it and check it to see if the error continues.

what actually happens?

I just tried it with a new phone (Android 5) and this works fine. How come?
