I'm using the BlueSMIRF Gold Bluetooth module but it seems like its only receiving data but not transmitting data. I've tried running it at 38400 baud and 115200 baud but transmitting doesnt work. Also tried running it at 3.3V and 5V but still transmitting doesnt work.
For my receiving test I transmitted the character 'a' from my Mac's bluetooth and my Axon received the 'a' - success for receiving data from laptop.
However when I try to send data out the BlueSMIRF so my Mac can receive data, I don't receive any data. Keep in mind that the bluetooth status light shows that it is in fact connected and my Mac also shows the BlueSMIRF as connected. I've also tried jumpering together the two Flow Control pins - CTS and RTS - but still transmit doesnt work
Whats even stranger is that if I send the BlueSMIRF the '$$$' command , or the wireless setup command, from my Mac's bluetooth, it responds and the Mac receives bluetooth settings information from the BlueSMIRF. So I can set any settings I want on the BlueSMIRF and I get all the 'AOK' confirmation messages that the BlueSMIRF transmits.
I'm using Zterm on Mac as my serial terminal software and I double checked that all the settings are correct. I also checked and my wiring is good.
Any ideas on what to try?
