Hi, I was wondering if 2 bluetooth modems can communicate peer to peer or do they need a dongle to be a master? So far i’ve been using a pc to control my bluetooth robot and it works great. Now, i’d like to build a remote control and not use a pc at all. Can someone please give me some suggestions. Thanks.

depends exactly on how you set it up, but any bluetooth device can be the master, that’s in fact how their point to point networking system works, no system is dedicated to be a slave unless it’s protocol is set that way, with the modems you have extreme control.
Look at the command sheet, specifically “ATDM,,”.
You’ll want to send something like this to connect to the device with address 11:22:33:44:55:66```
ATDM,112233445566,1101

exactly, and then once paired both devices act as peers, that’s how bluetooth works 
Sorry to revive a 5 year old thread, but I tired to do peer to peer with my bluesmirf and these commands don’t seem to be valid anymore. Does anyone know if there is a new way to do this? Also, once they are connected, how can I input an ACTION command so that it returns a value while the two bluesmirf modems remain connected?
