It appears to me that since Handy FW 4 came out, BT is the way to go. BT used to be pretty bad.
Via wifi there are many issues as of late, like disconnecting during session which is the worst. Skipping around scene you need to pause/play the script to get it going again. Other issues also.
Pros of going with BT:
- no loading of script, instant connection. This is really nice when switching back from Manual mode, wifi has to reload the script EVERY time
- No drop outs with the connection... at all ever
- Script accuracy with Handy appears to be the same as wifi
I'm using Q3 SLR via DeoVR with the Handy OG and here is how you connect BT.
Go to Settings from the Grid, then Haptics, then make sure Handy option is Disabled, Put your Handy into BT mode by holding bottom button 3-4 seconds > it will blink blue/purple, then add the BT device with the bottom option (for future sessions it will automatically connect now).
TIP: press the Up button on the Handy until you max it out. You need to do this only one time if it appears the range isn't fully working.
Give BT a try & report back here with your opinions...
