I'm currently using the DSPS program for the DA14580. I understand that the DSPS contains buffers for out and inbound transmission in regards to the host microcontroller, my question is what size are these buffers by default, can this size be changed and what are the size limitations?
Also, what is the expected behaviour of the DSPS if a host microcontroller writes to the buffer continuously while no bluetooth device is connected? I found the device stops operating, but should I be monitoring the flow control hardware lines after writing each individual character? Or is there a way to detect if a device is connected?
