    WIRELESS CONNECTIVITY & SENSORS ANR014 - Connect a smart phone to a Proteus Bluetooth LE module 4 Quick start The following description demonstrates how to setup a connection with a smart phone to a Proteus radio module. The smart phone acts as central device. In the next chapter the WE Bluetooth LE Terminal App is used.
  • Page 12 WIRELESS CONNECTIVITY & SENSORS ANR014 - Connect a smart phone to a Proteus Bluetooth LE module 4. By default, the module is advertising. Thus, one LED of the Proteus EV-Board is blinking. ® Start your smart phone, enable the Bluetooth LE and location feature and open the WE Bluetooth LE Terminal App.
  • Page 13 WIRELESS CONNECTIVITY & SENSORS ANR014 - Connect a smart phone to a Proteus Bluetooth LE module 8. As soon as the module has been chosen, the connection setup starts. When the module has received the connection request, it’s LED_1 (LED_3 on the Proteus-EV) will con- stantly light up.
  • Page 14 WIRELESS CONNECTIVITY & SENSORS ANR014 - Connect a smart phone to a Proteus Bluetooth LE module 11. On the Proteus side, the radio module has sent the corresponding CMD_CONNECT_IND and CMD_CHANNELOPEN_RSP in between. These messages indicate that a connection has been setup and a link has been opened.

To send back data (here we choose 0xDE 0xAD 0xBE 0xEF) to the smart phone a CMD_DATA_REQ message must be sent to the module from the host. The format of the CMD_DATA_REQ message is as follows, where the check sum (CS) is calculated as XOR of the preceding bytes: Start signal...
  • Page 17 WIRELESS CONNECTIVITY & SENSORS ANR014 - Connect a smart phone to a Proteus Bluetooth LE module 16. When sending the CMD_DATA_REQ to the Proteus module, it responds with two different messages. First a CMD_DATA_CNF message is returned, as soon as the request was inter- preted.
