The \"PB13\/SPI_SCK\/BOOT\" pin is used to control LoRa-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the \"Boot\" button on LoRa-E5 Dev Board or LoRa-E5 mini), the module will stay in the bootloader, and keep transmitting \"C\" character every 1S at baud rate 115200.\n  \u003c\/p\u003e\n \u003c\/div\u003e\n \u003cdiv\u003e\n  \u003cblockquote\u003e\n   \u003cp data-style=\"font-weight: bold; margin-top: 10px;\"\u003e\n    \u003cstrong\u003e\n     Attention\n    \u003c\/strong\u003e\n   \u003c\/p\u003e\n   \u003cp\u003e\n    1.

The \"PB13\/SPI_SCK\/BOOT\" pin on the LoRa-E5 module is just a normal GPIO, not the \"BOOT0\" pin of the MCU. This \"PB13\/SPI_SCK\/BOOT\" pin is used in the bootloader of the Factory AT firmware, to decide to jump to APP or stay in bootloader(for DFU). The real \"BOOT0\" pin doesn't pinout to the module, so developers need to be careful when developing low-power applications.\n   \u003c\/p\u003e\n  \u003c\/blockquote\u003e\n  \u003cp dir=\"ltr\"\u003e\n   \u003cstrong\u003e\n    \u003cspan data-style=\"font-size: medium;\"\u003e\n     2.
