I am at EMC testing and we are trying to do Bluetooth coexistence testing. Initially I thought I would just use the Tinker program and the Particle app to show connectivity. When in a big metal box and not connected to the cloud, the app does not communicate with Bluetooth. It keeps trying to connect and doesn’t run the program.
I have SYSTEM_MODE(SEMI_AUTOMATIC) so the program can run without being connected to the cloud. This is not working.
Any thoughts on how I can have Bluetooth active without wifi?
