Make sure WILC SD is inserted (if using SAMA5D27-SOM1-EK). 2. The image will connect automatically to the following credentials: **SSID**: MASTERS **Passphrase**: microchip 3. if the AP was not up at boot, or you wish to connect to another AP, use: > * killall wpa_supplicant udhcpc > * cd iot8 > * ./start_sta_pass_args.sh SSID Password # Heart rate monitoring 1. Edit demo/SendDataToAzureCloud.py line 20 with your device connection string 2. Edit demo/SendDataToAzureCloud.py line 91 with your device ID 3. Edit Heart-rate-web-app/public/javascript/index.js line 136 with the device ID 4.

Please follow the following steps: 1. Clone Linux4sam buildroot: - For SAMA5D27-SOM1-EK: > clone https://github.com/linux4sam/buildroot-at91.git -b linux4sam_6.0 - For SAMA5D27-WLSOM1-EK: > clone https://github.com/linux4sam/buildroot-at91.git -b sama5d27wlsom1ek_1.0 2. Get the external buildroot by cloning this repo: > clone https://github.com/MicrochipTech/Azure-IoT-Heart-rate-monitor.git 3. Navigate to buildroot directory: > cd buildroot-at91/ 4. Make sure you really cloned the suitable tag: > git branch 5. Do your modifications as desired in external buildroot Azure-IoT-Heart-rate-monitor/buildroot_external/ 6. Build buildroot using your modified external buildroot: - For SAMA5D27-SOM1-EK: > BR2_EXTERNAL=../Azure-IoT-Heart-rate-monitor/buildroot_external/ make sama5d27_som1_ek_wilc_defconfig - For SAMA5D27-WLSOM1-EK: > BR2_EXTERNAL=../Azure-IoT-Heart-rate-monitor/buildroot_external/ make sama5d27_wlsom1_ek_defconfig - Then, > make # Have questions/comments?
