I have a Bluesmirf silver that I’ve set to automatically connect with a device, so it’s always in data mode. Although this might vary by hardware, is there anyway for the smirf to send any kind of confirmation to the microcontroller(either BS2 or Arduino) about the state of its connection? The tx and rx pin seems to fluctuate randomly in the values i read from them.
Would hooking up CTS to my microcontroller be able to indicate this?
