Sog Yang / Mbed OS NNN50_BLEWIFISensor

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.

  1. Download or build a TCP Server on you host computer
    1. Please find out the TCP server code or install TCP server application in your host computer.
  2. Import this sample application and setup these information about AP & TCP Server
    1. *char* AP_SSID = "SOG";
    2. *char* AP_PWD = "1122334455667788";
    3. *char* TCP_SERVER_ADDRESS = "10.0.1.13";
    4. *int TCP_SERVER_PORT = 1030;
  3. Compiler your code and download to your mBed device.
  4. Control your mBed device
    1. 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
0x000x020xA1
