I need to know if I'm the only one having this little... inconvenience.
I recently purchased a Bad Elf GPS Pro+ to improve the accuracy of my field data collection.
I have configured all the parameters correctly, when I launch the Survey123 application it detects the receiver well and I receive the data. What bothers me is the fact that there is always a difference between what my receiver gives me as precision data (see attachment - 2.3 meters in that case) and what Survey or my phone receives and shares as information (3.2 meters). On average, this is a difference of 1 meter - 1.5 meters. It might not be much, but I don't understand why.
I tested with two old Android phones (android 9) and my Survey123 app is up to date (version 3.17.66). I tested with Field Maps and same thing.
So is this normal? Is this a problem possibly related to my Bluetooth connection or just my phone?
