I was wondering if it is possible to create a bluetooth device which would have a LCD screen and some memory (1kb) for making and receiving calls.
From my research ( and I am far from an EE, but trying to learn as I go) i found that arduino doesnt support HFP or HSP. What Id like the device do is, go through a small list of numbers on lcd, choose one and make a call through the bluetooth connection to a smartphone.
Any help is appreciated.
EDIT. so while looking online a found a BT module RN-52, has both SSP and HFP/HSP, and when looking at the PDF for the RN-52 Evaluation kit i found on page 24 that it has a command to call any phone number that it is given. http://ww1.microchip.com/downloads/en/DeviceDoc/rn-bt-audio-ug-2.0r.pdf
My question now is. Can it be connected to an arduino uno, so that it can send a number to the rn-52, so it can call it?
