I have a bluesmirf gold that I wanted to use the cts and rts pins but I’m finding a lack of material on how to use them.
So far and to my understanding both rts and cts are active low.
so setting the cts pin high, I’m expecting rts to go high as well if it recieves data.
Am I correct in this thought.
My setup currently is a bluetooth usb key hooked up to my computer.
The bluesmirf is connected to a picaxe for initial testing.
The bluesmirf is set to 4800 n, 8, 1 and mode is set to 3 (mdm or as it’s said in the manual, modem controls)
I’ve hooked up rts to a transistor as to trigger an led so I know it’s changed state.
I have tried both with cts low and cts high to set this pin on the bluesmirf but I never get a state change on the rts pin when I said data to the bluesmirf.
cts low, rts = low when data comes in
cts high, rts = low when data comes in.
now I haven’t actually checked to see if data is coming in on the rx pin as of yet, I just wanted to make sure that I could do the handshaking first
Am I correct in expecting at least one of these cases to set the rts high though?
Ideally, I would use the rts to trigger an interupt on the picaxe to let it know a command is coming in and set the serin pin to read the rx data.
