When I try to get bytes from a BLE module I get this error. It doesn't matter if the full UUID or short UUIDs are used.
Other BLE testing apps have no trouble getting the data from the same UUIDS.
It should be noted in my debugging that the list of characteristics just repeats the same one instead of all the ones available. This looks like a bug but I'm new to AppInventor so I'm not sure.
Here is a PNG of the relevant block
Thank you for your assistance
