Does anyone have a solution to combine the Osmo Pocket Wireless Module with the Osmo Pocket 3.5mm Adapter
  

Hi there, thank you for reaching out and we really admire you being interested in using the Product. With regards to your question. I'm afraid this set up will not work since the port from the module supported on the charging the Osmo Pocket. Thank you for your consideration.

You mean is it possible to use the Wireless Module and the Mic Adaptor? If so, no. The USB-C port on the bottom of the Wireless Module is power only. You can charge your Osmo Pocket when it's placed in the Wireless Module, but the 3.5mm adapter doesn't function whilst plugged into the WIreless Module's USB-C.
