It seem to have a SPP profile and an audio profile. Having both on the same module can have it's interest, did any one tryed it? If so, any comment?
I bought one on Ebay that I've been working with. It's very sensitive to the voltage, 3.3 was not sufficient, I had to run 5V through a diode to get it to power up. I have not been able to get serial comms working to it yet, I'm fairly certain I finally found the right pinouts for it, but not all of them are labeled. If I saw the right device when it was powered up, it does not have the HSP or HFP that some of the specs claim, which was disappointing, but it does have a microphone input, which was confusing. If it's just meant to be an audio receiver, why have the mic inputs?
I'm still looking into this, trying to find a datasheet that isn't in Chinese, or someone who could translate it for me so I can find out for sure what each pin does. I'll let you know if I figure out any more on it.
have you work with the SPP of xs3868 ??
I wanna send a char to my phone by xs3868 ..
Is it possible by SPP of this module ?
