Thanks.. Out of interest which modules do you use? I had a look on their
website but there seemed to be no clear winner. They do however all seem
pretty complicated, obviously a result of spread spectrum. Have you looked
into Bluetooth at all? I gather that the chips can be upped to 100mw at
2.4ghz so that should give reasonable range. I had a look a couple of weeks
ago but again all seems pretty complicated.
