Clone this repository and use the build and deploy instructions from Snapcraft.

snapcraft --debug
sudo snap install edge-tools_1.0_amd64.snap --dangerous

Connect snap to the network-observe interface:

sudo snap connect edge-tools:network-observe

After installation, a daemon will check for network availability every 60 seconds:

ping api.snapcraft.io
ping lwm2m.us-east-1.mbedcloud.com
nc api.snapcraft.io 443
nc lwm2m.us-east-1.mbedcloud.com 443
edge-tools.test-lwm2m

The output is appended to:

/var/snap/edge-tools/common/daemon.txt

Note that the log file must be manually cleared to free up disk space. Log file will grow around 1 kilobyte per minute.

If you want to stop it from running, use the standard snap commands.

sudo snap stop edge-tools.daemon

and

sudo snap start edge-tools.daemon

to restart it.

Uninstallation can be done with:

sudo snap remove edge-tools

Use openssl to negotiate a TLS session with bilateral certificate verification.

For connecting to either bootstrap or LwM2M server run in a command prompt:

edge-tools.test-bootstrap

or

edge-tools.test-lwm2m

The command will either return success or print out the handshake failure. The full openssl output can be found in ~/snap/edge-tools/common/, in files test-bootstrap.txt and test-lwm2m.txt.
