( @hydronics your published code had a small bug, where you used
options instead of
options1, but that's just FYI.)
WebBLE says it supports it so I guess it should :-) However, it doesn't seem to work at the moment, and looking at the code it looks like I didn't implement it. Given I said it is supported I think I should make it so! I'll try and get an update submitted to Apple today or tomorrow.
Edit: also this might help @user73018
