HC-05 Char transmission

Projects General Guidance

Hi guys,

I wanna make empiricall SINR/BER dependence of Bluetooth module HC-05. So for observing errors I will transmit from one module to another bits 0 or 1 and interfere the signal using PR sequence from PXI. As I realized if I pass int values receiver get it in any case, but the closer RX to PN source the bigger delay. So for watching errors I think I have to transmit char values. But it doesn't work. Even without PXI, i have after my values in return something else. Somebody faced with this trouble earlier? Thank you.

A bluetooth module will be doing error correction for you, so that's going to disguise the underlying channel BER.

Perhaps all you can measure is packet error rate?

Can you explain this better?
