7 Boot LOG Instruction If you use a fixed baudrate, the UART sends MODEM STARTUP after the module is booted and +PBREADY after the phonebook is available. If you boot the module in automatic baudrate detection mode, enter AT to check if the AT function is initialized or not. The UART responds with if AT is initialized and outputs +PBREADY after the phoneboos is available. Copyright Neoway Technology Co., Ltd 1
