In the past few days, I used the nrf51822 driver mpu6050 and its data transmission to Android. The debugging process encountered some difficulties and the apptimer was not very useful. Then I took a look at the ble_app_hrs program, and the result was completed successfully, the value of the demo.
I suddenly remembered that noridc, in addition to an android NRF toobox 1.2 software, supported the collection of human information such as blood pressure (glucose), heart rate, body temperature, and so on. So I tried it and it was hard to get started, I thought it was a mobile phone problem, but Xiaomi officially said that Red Rice 1 S supports Bluetooth 4.0, which is an android 4.3 system, and then accidentallyRestart redmi.It seems that Nordic is not doing well with Bluetooth.
In addition, when we re-run the becon experiment, Android never detected my becon device, indicating that it could not be understood. It seems that Nordic is not doing well enough. After all, it is just a demo.
