Subject: [PATCH] Add TAG to all compile units (#2060)

When using static TAG is only valid in the current compile unit. For
some reason it seems that the current ESP8266/ESP32 compiler use the
instance from ble.cpp, but it seems that this causes issues with newer
compiler leading to compile time errors like this:
