GO-AT

A way to send AT command or something else to modem.

Develop base huawei mh5000-31

Usage

You can send some at commend that we packed.

package main

import (
   "fmt"

   devices "github.com/JackyCZJ/go-at"
   "github.com/albenik/go-serial/v2"

   huawei "github.com/JackyCZJ/go-at/huawei/mh5000-31"
)

func main() {

   opt := []serial.Option{
   	serial.WithDataBits(8),
   	serial.WithStopBits(serial.OneStopBit),
   	serial.WithBaudrate(devices.BaudRate),
   	serial.WithParity(serial.OddParity),
   }
   h := new(huawei.HUAWEI)
   h.Init("/dev/ttyUSB1", opt...)
   res, err := h.HCSQ()
   if err != nil {
   	fmt.Println("Got error result:", err)
   	return
   }
   for i := range res {
   	data, _ := res[i].Serialization()
   	fmt.Println(string(data))
   }

}

or send some command.

	opt := []serial.Option{
		serial.WithDataBits(8),
		serial.WithStopBits(serial.OneStopBit),
		serial.WithBaudrate(devices.BaudRate),
		serial.WithParity(serial.OddParity),
	}
	h := new(huawei.HUAWEI)
	h.Init("/dev/ttyUSB1", opt...)
	h.Cmd("...some command")

func (*Device) Cmd

func (d *Device) Cmd(command string) (result string, err error)

Cmd send command to devices and return result when result contains ok.

func (*Device) Connect

func (d *Device) Connect() (*serial.Port, error)

Connect : Connect to devices with configure.

func (*Device) SetPortName

func (d *Device) SetPortName(portName string)

SetPortName ,default will be /dev/ttyUSB1
