Yeah, never made sense to me either, we have seen with this particular board variability in performance. I would like to apply a coating to keep the BT module dry and be able to wash the board then remove the coating over the module.

Try immersing the assembly in IPA for 30 minutes. IPA is hydroscopic ans will drive off most of the water. Dry the assembly. Then bake at 110°C for 2 hours.
