User Manual

The rest of the script configuration depends on the overall requirements. The script explains which exact parameters are configured to be published.
Navigate to System>Scripts and add a new script there (name it, for example, script1).
To run the script, you can use the command line:
/system script run script1
HTTP fetch with script scenario
Another way to publish data is to use HTTP (instead of MQTT). This can be achieved using .fetch tool
The same principles apply:
Create a new script, use the template as a reference, change the parameters accordingly and run the script.
Every line that begins with a symbol " " is instructional and it describes the parameter that is going to be configured below the line. Change the parameters #
within quotation marks "" that would apply to your specific case.
Script example:
# Required packages: iot
################################ Configuration ################################
# Interface whose MAC should be used as 'Locator ID'
:local locatorIface "ether1"
# POSIX regex for filtering advertisement Bluetooth addresses. E.g. "^BC:33:AC"
# would only include addresses which start with those 3 octets.
# To disable this filter, set it to ""
:local addressRegex ""
# POSIX regex for filtering Bluetooth advertisements based on their data. Same
# usage as with 'addressRegex'.
:local advertisingDataRegex ""
# Signal strength filter. E.g. -40 would only include Bluetooth advertisements
# whose signal strength is stronger than -40dBm.
# To disable this filter, set it to ""
:local rssiThreshold ""
