Sensors not working with Bittle X through bluetooth

Hello, I have recently bought a Bittle X as well as the sensor pack. I have connected the touch sensor to the BiBoard extension hat through one of the grove sockets (I believe it is the I36, I39 socket). When I connect my laptop to Bittle using a USB-C cable, and use the 'Digital Read BiBoard 36/39' block on Mind+, I can get the correct output (0 when the sensor isn't activated, 1 when it is). But when I try using Bluetooth, Mind+ just outputs 'None'. I can still program Bittle to move using Bluetooth, just can't get information from sensors.

Thanks, any help would be appreciated.
