Hi Oliver, I think that this is the most cost-effective solution: just buy another GPS receiver and pair it with another Unleashed.Oliver wrote: ↑October 14th, 2020, 4:02 pm3) If you're in a situation where some GPS receivers might not have reception, but the smarpthone does still have a position (from its internal or an external smartphone, chances are extremly high that the precision of that GPS position you still have is WAY worse than the maximum range of BLE. In other words, those (maximally) 40m are not going to make a difference.
Nonetheless, for this special case that you drew, you're simply going to have to buy a dedicated GPS receiver for that one Unleashed that's 40m away from the others, and set that Unleashed to only use GPS data from the external source, whereas the others close to the smartphone can be set to external with smartphone fallback.
