Seeed / Mbed OS pelion-example-common Featured

Specific Pelion ready example using features of Seeed Wio boards including cellular and SD Card

Dependencies:   WS2812 PixelArray

Fork of simple-mbed-cloud-example-wio_3g by Toyomasa Watarai

This example is known to work great on the following platforms:
Seeed Wio 3G and Seeed Wio LTE-M1/NB1(BG96) over cellular and using SD card.

Follow the Quick-Start instructions: https://cloud.mbed.com/quick-start

Example functionality

This example showcases the following device functionality:

• Allow the user to change the state of the board LED from Pelion LWM2M led_state resource and PUT request.

Instructions to use this program with mbed CLI

1. Import the application into your desktop:

mbed import https://os.mbed.com/teams/Seeed/code/pelion-example-common/

cd pelion-example-common

2. Install the CLOUD_SDK_API_KEY

mbed config -G CLOUD_SDK_API_KEY <PELION_DM_API_KEY>

For instructions on how to generate your API key, please see the documentation.

3. Initialize firmware credentials (done once per repository). You can use the following command:

mbed dm init -d "<your company name in Pelion DM>" --model-name "<product model identifier>" -q --force

If above command do not work for your Mbed CLI, please consider upgrading Mbed CLI to version 1.9.x or above.

• Set APN name, username and password in the mbed_app.json.

            "nsapi.default-cellular-plmn"      : "\"00000\"",
            "nsapi.default-cellular-sim-pin"   : "\"0000\"",
            "nsapi.default-cellular-apn"       : "\"apn\"",
            "nsapi.default-cellular-username"  : "\"username\"",
            "nsapi.default-cellular-password"  : "\"password\""

4. Compile and program:

mbed compile -t <toolchain> -m WIO_3G

(supported toolchains : GCC_ARM / ARM / IAR)

Troubleshooting

• Make sure the fields nsapi.default-cellular-sim-pin, nsapi.default-cellular-apn, nsapi.default-cellular-username and nsapi.default-cellular-password from the mbed_app.json file are filled in correctly. The correct values should appear in the user manual in the details of the SIM card.
• Enable trace flag to have access to debug information "mbed-trace.enable": true.
• Try both TCP and UDP socket types.
• Try both "lwip.ppp-enabled": true and "lwip.ppp-enabled": false.
• The modem and network may only support IPv6 in which case "lwip.ipv6-enabled": true shall be defined.
• The SIM and modem must have compatible cellular technology (3G, 4G, NB-IoT, ...) supported and cellular network available.
