So im actually using an arduino in this case but the code isnt the issue here im getting really frustrated! Im using the Rocket Brand Studios BT remote app for robots on my phone and pairing with the HC05. The HC05 can transmit data to my phone just fine the app and serial consoles show all the data I transmit. The issue is when I send data from my phone to the module it doesnt seem to receive anything, ive tested the serial port for any input what so ever and im not getting any when I use the HC05. Im wondering if this may be a common issue I have Rx to Tx and Tx to Rx between the hc05 and arduino chip and then 5v pwr and grnd maybe i need some pulle up resistors or something....

    Ok well this is weird Ive tested this thing using a com connection and putty and the parallax terminal on the PC via bluetooth and hardwire and neither will let me send data to the robot... the arduino terminal will let me send data though hardwire com port but thats it, nothing will allow me to send to the bluetooth module and most programs wont allow me to send data over the hardwire either. This is getting really frustrating.

    rwgast, did you ever solve this problem? I'm running into the same thing.

    Thanks,

    You may want to email rwgast directly. He does not spend much time on the forums any more.
