Description
Just found this out on my BTT Pro V1.1 using Marlin 2.0.6.
When selecting #define SDCARD_CONNECTION ONBOARD (Configuration_adv.h), the TF cloud device will not start the Blue led blinking (when trying to connect to WIFI) and as a result, can not connect to the device via computer for file transfer.
By changing this selection to #define SDCARD_CONNECTION LCD (Configuration_adv.h) will allow the TF cloud to connect for usage.

Research direction
Start with the Marlin 2.0.6 configuration in Configuration_adv.h and reproduce the connection behavior with SDCARD_CONNECTION set to ONBOARD, then compare it with LCD. Trace the TF cloud startup and WiFi connection path affected by that setting. Done means the Blue LED begins blinking and the device accepts computer file transfers with ONBOARD selected.
