Difference between the old BlueSmirf and FireFly?

Wireless & IoT

Hi,

the old BlueSmirfs I used to buy came with a device name of SparkFun-BT or BlueRadio. I could just plug these units into my circuit and they would work. (used to control them using hyperterminal through a bluetooth dongle).

Anyway of late the bluesmirfs I’ve been receiving come with the device name FireFly. and these just don’t respond.

They get discovered, and I can even connect to them (the light even turns red)

but it won’t respond to either +++ or $$$ command

I’ve tried changing the baud rate from 9600 to 115k -doesn’t work

I tried using the default “1234” passkey and even removing the security setting all together -doesn’t work

any idea what the problem could be.

I really wish spark fun would provide proper documention when they change a part.

ok i figured out what the problem was… it allows you to login into command mode only for 60 sec after the unit is powered on.

Anyway I really don’t like how the new fireware handles its commands, i hope sparkfun reverts back to their old units
