BLE-WiFi with BIOSensors
Dependencies: AS7000 BNO055 NNN50_WIFI_API
DELTA NNN50 (Bluetooth LE 4.X & 802.11 b/g/n) with Bio Sensor (HRM, 9DoF motion Sensor) reference design.
Env. Setup step by step.
- Download or build a TCP Server on you host computer
- Please find out the TCP server code or install TCP server application in your host computer.
- Import this sample application and setup these information about AP & TCP Server
- *char* AP_SSID = "SOG";
- *char* AP_PWD = "1122334455667788";
- *char* TCP_SERVER_ADDRESS = "10.0.1.13";
- *int TCP_SERVER_PORT = 1030;
- Compiler your code and download to your mBed device.
- Control your mBed device
- Please use NORDSemi nRF Tool and setup and watch these information: GATT CMD: 0x00 (connect to AP, TCP Server, and create TCP socket), 0x02 disconnection TCP server, close socket, and WiFi sleep), 0xA1 (send sensor data to tcp server from out_buffer[]) and Status will be update by Bluetooth LE adv through manufacturing information
| 0x00 | 0x02 | 0xA1 |
|---|---|---|
| WiFi,AP&TCP Server connect | WiFi,AP, & TCP Server disconnect | Send sensor data to TCP Server |
