How to reset a Bluesmirf device?

One of my bluetooth devices doesn’t seem to go in command mode anymore when using goSerial (other devices do work with this program, so it’s not a software issue). It does connect, but it gives no feedback anymore giving the $$$ character to put this device in command mode. So i thaught of resetting this device. After searching in the documentation it seems i have to toggle three time PIO 4, but this seems a bit unrealistic as this input/output is solved on the bluetooth chip. How do i reset this BlueSmirf device the easy way?

Ok, i think i did a reset (using PIO 4 at the bluetooth chip, after 3 times toggeling, it rebooted my device, so i think it worked). But i still can’t go in command mode with goSerial. I don’t get it, this worked before and still works for other bluetooth devices… i can connect (flashing red led turns into green), but that’s it. if i typ $$$, no reponds. What could be wrong here?
