To enable re-programming of the module, UART signals connected to host must not interfere with
the flashing procedure. UART pins must be put in tri-state by host or have the possibility to
disconnect completely. Another option is to let host software handle the update procedure (e.g.,
implement the XMODEM protocol or a UART pass-through function).
