I am having problems getting the Bluesmirf Mate Silver (RN-42) into command mode once I have switched to HID mode. I have bought a second new Bluesmirf Mate Silver to confirm my issue.
I soldered the Bluesmirf and connecting to Arduino Uno. I used the ‘Example code: Using Command Mode’ from https://learn.sparkfun.com/tutorials/using-the-bluesmirf to successfully enter command mode.
I then entered the following commands in command mode (leaving out the comments):
SM,5 // Mode = 5, (any) Auto reconnect SA,2 // Authentication Mode 2 (SSP, "just works" mode) S-,myName // // Set BT Name, This short name with no spaces is Picked up ok on windows S~,6 // Enable HID on reboot R,1 // Reboot to lock in perameters
Next I use a PC and pair with the bluetooth ‘keyboard’ I have created above. I am able to use the Bluetooth and Arduino sketches to write into notepad on the bluetooth connected PC.
However now I cannot get back into command mode to make changes to the Bluesmirf config. Trying to use the example code above I can see ‘
$$$U,9600,N’ typed into notepad on the connected PC each time I load the sketch, rather than being used to enter command mode.
How do I get back into command mode after HID mode has been triggered.
