Setting baud on BlueSMiRF RP-SMA

Wireless & IoT
1

Hi all,

I am attempting to use the BlueSMiRF RP-SMA to connect my Arduino to my Android phone using Amarino. I’ve gotten as far as the phone being able to connect to the device and the light turning green.

Apparently it can only communicate using 57600 baud. How do I change this on the module? (I’ve found the documentation to be pretty sparse for someone with very limited experience in BlueTooth.)

Also, is it necessary to connect the CTS-1 and the RTS-0 to each other?

Thanks,

Sam

The default baud rate is 115200. If you are not using flow control connect clear to send to request to send.

See page 27 of the UM for info on what AT cmds to send the module for changing the baud:

The cmd sequence should go something like this:

AT,9600 (or whatever baud you are looking for)
