jpl-pfungst:
Hello,I had a lots of problems with HC05 and HC06, but at the end I have solved all of them.
I have 2 test programms one to be the master and an other to be the slave.
once connected they both read and write.they allow you to check the speed and the default mode of working. Some are only accept uppercase commands some only lower case and some any case will work.
The programm tests all the cases and show you what is working and whatis not.
I can send the code to any one interrested.
please do post the code.
