Start and stop node

[aprylwine]

Can't start and stop the scanning using the following:

he node will begin scanning after it is deployed, and will not stop until it is deployed again. It can be useful to turn on and off scanning to conserve energy and force scan requests to be sent triggering devices to respond. To control scanning, you may send a message containing msg.payload.scan=false to turn off scanning, and msg.payload.scan=true to turn it on.

This works for me on Mac OS. Please let me know what platform you are using. Here is a sample flow:

[{"id":"1e16b965.4a72b7","type":"scan ble","z":"4a370b8c.b8f334","uuids":"","duplicates":false,"name":"","x":606.5,"y":385,"wires":[["2aff3b2e.ec22f4"]]},{"id":"8b56c9d7.079d18","type":"inject","z":"4a370b8c.b8f334","name":"","topic":"","payload":"{\"scan\":true}","payloadType":"json","repeat":"","crontab":"","once":false,"x":307,"y":354,"wires":[["1e16b965.4a72b7"]]},{"id":"2aff3b2e.ec22f4","type":"debug","z":"4a370b8c.b8f334","name":"","active":true,"console":"false","complete":"false","x":821,"y":340,"wires":[]},{"id":"36937f8e.fc358","type":"inject","z":"4a370b8c.b8f334","name":"","topic":"","payload":"{\"scan\":false}","payloadType":"json","repeat":"","crontab":"","once":false,"x":313,"y":412,"wires":[["1e16b965.4a72b7"]]}]

Thank you for that example!

@aprylwine can you show an example of the flow you are using or how you set the scan property? Similar to @mblackstock's example, setting {"scan": false} in the payload should work.

There is a strict equality check in the code, so it must be set as a boolean, {"scan": "false"} or {"scan": 0} etc. won't cut it.
