lora Initialization

Parameters

Incoming Value Type	Explanation
string	lora Model, currently supported： llcc68 sx1268
table	lora Configuration parameters, device-specific

Return Value

None

Examples

lora.init("llcc68",
    {
        id = 0,           -- SPI id
        cs = pin.PB04,    -- SPI If there is no pin library, just fill in the GPIO number for the selected GPIO number.
        res = pin.PB00,   -- The GPIO number connected to the reset pin. If there is no pin library, just fill in the GPIO number.
        busy = pin.PB01,  -- Busy detecting the GPIO number of the foot
        dio1 = pin.PB06,  -- Data input interrupt pin
        lora_init = true  -- Whether to send an initialization command. If it is read directly after waking up, pass false
    }
