Using the sylvac UL 4 Each time I invoke the (send data) function the sylvac LED panel reports 'no.data'. To mention the obvious but nothing is received at the connected USB device.
My question is. . How do force the sylvac device to (have data) to send? Can anyone explain what this 'no.data' actually means from the calipers perspective?
This might be a good place to start
Take a look at IOT-Ready Sylvac Bluetooth® Profiles, and SYLVAC BLUETOOTH IOT 4.0 / KEYBOARD INPUT FUNCTION. WIRELESS DATA TRANSFER
As briefly mentioned above, you need to either connect the caliper to one of the software "masters" offered by Sylvac, or use the caliper in HId mode.
Select your model from this page: Sylvac Hand Tools.
Download the appropriate manual; the other answers here do not refer to your appropriate model manual.
Enable the HId mode through a sequence that might look like this below. Please note that some calipers don't have HId mode.
No.data: Value could not be sent via Bluetooth® Technology. Check the Bluetooth® connection on instrument and master device (on/off). Check if you are within the max. transmission range 5-15m.

I have now resolved this issue in my case: the caliper's BT connection needs to be set up using the app that Sylvac has made for this. Note, if you've used the phone's BT procedure, it's the wrong way.

Not sure if this is the sole cause for this (no.Data) error but. . . Sitting the Bluetooth profile to (Hld) - (Virtual Keyboard) seems to have corrected this issue. Measurement data arrives (in the app that has focus / cursor) as if this caliper were a keyboard attached to the PC. Very smooth and nice with a carriage return - linefeed appended.
