Hello, i have a question.
Can nRF51822(s120) handle more than one connection at same time?
Let me explain: i have one server(nRF51), and two(or more) clients(nRF51 and mobile...
I've got an application that does a lot of nRF51822 GPIO wiggling and the timing needs to be controlled. In one spot I simply set a pin high then low like this:
