if I enter the command:
pi@domoticz1:~ $ hcitool name <mac_address_of_my_phone>
it will give me the Bluetooth name of my phone (if within reach)

If I try in a script:

Code: Select all

return {
        on = {
               timer = {
			'every minute',
		},
        shellCommandResponses = {
            scriptVar,
        },
	},
	logging = {
		level = domoticz.LOG_DEBUG,
		marker = 'Ben ik thuis',
	},
	execute = function(domoticz, item)
		domoticz.log('Timer event was triggered by ' .. item.trigger, domoticz.LOG_INFO)
		if item.isTimer then
			domoticz.log('Item is Timer')
			domoticz.executeShellCommand(
            {
                command = 'hcitool name xx:xx:xx:xx:xx:xx',
                callback = scriptVar,
                timeout = 20,
            })
		elseif item.isShellCommandResponse then
			domoticz.log('Response from shell command')
		end
		domoticz.utils.dumpTable(item)
	end
}

The callback is always nil and shellCommandResponses is never triggered.
the log:

You forgot to give the variable scriptVar a value and therewith it is always nil.
try

Code: Select all

local scriptVar = 'something'

return {
        on = {
               timer = {
			'every minute',
		},
        shellCommandResponses = {
            scriptVar,
        },
	},
	logging = {
		level = domoticz.LOG_DEBUG,
		marker = 'Ben ik thuis',
	},
	execute = function(domoticz, item)
		domoticz.log('Timer event was triggered by ' .. item.trigger, domoticz.LOG_INFO)
		if item.isTimer then
			domoticz.log('Item is Timer')
			domoticz.executeShellCommand(
            {
                command = 'hcitool name xx:xx:xx:xx:xx:xx',
                callback = scriptVar,
                timeout = 20,
            })
		elseif item.isShellCommandResponse then
			domoticz.log('Response from shell command')
		end
		domoticz.utils.dumpTable(item)
	end
}
