Make a pair of bluetooth-enabled devices that communicate with one another? Answered
My question is if it's possible to build such a pair of devices, that would sustain a two-way communication channel between them. Basically, both devices would have to be a central AND a peripheral. Specifically, I need it for testing their reactions to each others proximity. (So that they would both need to react simultaneously.)
And if it's possible, how?
(At least some literature.)
