== Notes and version constraints ==
* The provided source contains no explicit compatibility statements for all Raspberry Pi models; the FAQ only confirms support for Raspberry Pi 4 Model B on the related SIM7600G-H model.
* MMS is not supported by the SIM7600x series.
* The reset pin was not brought out because it only resets a subset of functions (similar to AT+CRESET).
* If the sim7600_4G_hat_init command fails, ensure the /home/pi/SIM7600X directory is correctly copied and permissions are set.
* When compiling the BCM2835 library, running 'autoreconf -vfi' may be required.
* After enabling GPS, the NMEA port may not output data without the listed AT commands; a module restart is needed afterward.
* For the new HAT: PWR and 3V3 are shorted by default for automatic power-on; remove the jumper for manual operation.
* Flight mode is disabled by default on the new HAT; set the jumper between Flight and D4 to control it via Raspberry Pi pins.
