Hi all,
I had an issue with the communication using my blueradios module as a wireless serial port
After a long time having troubles, I found the cause of all the trouble:
The voltage on which the RX and TX signals from the microcontroller were 5 volts, whilst the blueradios module works with 3.3 volts.
I decreased the voltage on my microcontroller (arduino mini) to 3.3V and then the problems were gone!
I hope some more of you struggle with the same and are helped with this post
