I need to interface Bluetooth® DIP Module - SparkFun WRL-08461 module with my PC serial port. I used max ic circuit to interface. But i cant input commands from hyper terminal module does not response them. Plz help me. Module says its operation voltage is 3.3 v what does it mean. Max ic TX RX voltage is 5v should i use voltage divider when connecting it to module RX TX. Plz give me an A to Z idea about this interfacing. I really want in put AT commands from hyper terminal.
Hajan:
i also need to interface my RN 41 DIP module to the PC(Thro Serial port). Can some one send me the circuit diagram for this particular testing?raala can you please forward me the cct diagram to the mail address
Please help me…
Now i want to ask that can you give me a clear idea about why do we need Logic level converter here with RN 41 bluetooth module? I want to interface RN 41 DIP bluetooth module with the MAX3232 IC(Operational voltage is 3V-5.5V)
So here do i need to consider about the logic level converter or Can i connect bluetooth module to the MAX IC directly…Please guide me…
Nope, you don’t need a level translation for that.
Just run the MAX3232 and Bluetooth from the same power supply.
Thanks for your point. One more question… That is what is the role of the level converter… Can you please explain it…
Raala Use MAX 3232 IC to interface
