Sorry，my English is poor. I Now,I have four uart BLE device. Every device sends data in frequency 20Hz. And I also have a android phone. I hope that the phone could receive the data from the four devices simultaneously. I read this question link text . And I add 3 BluetoothGatt objects and callbacks , so every device has a BluetoothGatt object and a callback. I modify the nrfUARTv2.apk to achieve it. But I failed. Phone only reveived data from one device that I connected recently. And am I doing this right? Please give me some suggestions. I'm looking forward to your help. Thank you!
