I have no WLL experience so short answer is I don’t know. But the loop_request setting is a vantage driver setting, as far as I know you need to use a different driver for WLL. Also, there are a number of WLL drivers; looking at one just now I see it appears to emit pressure and altimeter, though as I said I don’t know enough about WLL to draw any conclusions.
