+The C application code in this folder is no longer in use, except `stub.c` and `vsscanf.c`
+
+[`src`](src): Stub application source files in C for Mynewt build. These C files are compiled into the Mynewt ROM image. These files are stubs, the actual application source files have been ported to Rust in [`/src`](/src)
+
+[`src/stub.c`](src/stub.c): Low-level C functions needed for the Mynewt application
+
+[`src/vsscanf.c`](src/vsscanf.c): Patched version of `apps/my_sensor_app/src/vsscanf.c` that
+fixes ESP8266 response parsing bugs.  The patched file must be present in that location.
