Overview

• This application introduce the MQTT Client with WIFI and BLE usage by TI simplelink launchPad.

Dependencies

• The application relies on many TI and many third party software libraries. The following libraries need to be available:
  • SIMPLELINK-MSP432-SDK
  • SIMPLELINK-SDK-BLUETOOTH-PLUGIN
  • SIMPLELINK-SDK-WIFI-PLUGIN
  • UniFlash
  • ARM-CGT
  • FreeRTOS

Build

~$ ./build.sh

• Or like following the command but you should create intermediate files to store these variables before building.

mkdir build && cd build
cmake -DSIMPLELINK_MSP432E4_SDK_INSTALL_DIR=${SIMPLELINK_MSP432E4_SDK_INSTALL_DIR} \
      -DSIMPLELINK_MSP432_SDK_WIFI_PLUGIN_INSTALL_DIR=${SIMPLELINK_MSP432_SDK_WIFI_PLUGIN_INSTALL_DIR} \
      -DSIMPLELINK_SDK_BLE_PLUGIN_INSTALL_DIR=${SIMPLELINK_SDK_BLE_PLUGIN_INSTALL_DIR} \
      -DMSP432_TOOLCHAIN_PATH=${MSP432_TOOLCHAIN_PATH} \
      -DSYSCFG_TOOL_PATH=${SYSCFG_TOOL_PATH} \
      -DUSE_IPV6=OFF \
      -DSSID_NAME="${ssid_name}" \
      -DSSID_PWD="${ssid_pwd}" \
      -DMQTT_USER="${mqtt_user}" \
      -DMQTT_PWD="${mqtt_pwd}"  \
      -DMQTT_SRV_IP="${mqtt_srv_ip}" \
      -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON ../
