I AM USING SIM808 MODULE
When I connect SIM808 using smartphone the connection seems to get HFP by default.
what if I want to use SPP can we change it in process?
How to make spp as default profile.
if not how to transfer data from phone to Modem in HFP mode?
I would like to connect modem using smartphone and then transfer data from smartphone.
Please help on this.
Thankyou
