Hi, I am written an app which connect the device by bluetooth low energy(BLE), and I want to use my app to connect with the nordic nrf51422, but when I try the app on my iPhone, the app do can searched the device, but when I click it and choose to connect, it will show me Connection Successful and then automatically shut down.
So I am wondering is my code got problem or the nordic chip won't allow the unofficial nordic app to connect?
This link is the code I used: https://julianocustodio.com/2017/12/07/bluetooth/
