Hi guohui, thanks for the response. Yes, I did read that document and it didn’t help much with understanding how to communicate via Bluetooth. Like I said, it’s my first time working with BLE, and excuse me for my ignorance but I’m a bit skeptical as to how these two devices cannot pair to each other if they both have built-in BLE modules? From my limited understanding of Bluetooth, all you need is to setup one as a peripheral and another as a central device so that one is advertising and the other picks that up and communicates through that connection. Please correct me if my understanding is wrong.
I might try a couple wireless Arduino HC-05 Bluetooth adapters instead to communicate with one another. Thanks!
