[BUG]qmodem_init脚本错误? 拨号总览，有两个拨号状态问题#75|Fuck H29K

[im-zhou]

问题同#75

经查以下代码

QModem/application/qmodem/files/etc/init.d/qmodem_init

Lines 70 to 80 in 8fd3991

	_try_usb_device()
	{
	config_get data_interface $1 data_interface
	[ "$data_interface" == "usb" ] && _try_device
	}
	_try_pcie_device()
	{
	config_get data_interface $1 data_interface
	[ "$data_interface" == "pcie" ] && _try_device
	}

在调用中, _try_device并没有传参, 导致_try_device实际并不会有效执行

QModem/application/qmodem/files/etc/init.d/qmodem_init

Lines 127 to 152 in 8fd3991

	_try_device()
	{
	config_get path "$1" path
	config_get type "$1" type
	config_get network "$1" network
	case "$type" in
	usb)
	path="/sys/bus/usb/devices/${path}"
	;;
	pcie)
	path="/sys/bus/pci/devices/${path}"
	;;
	esac
	if [ ! -d "$path" ]; then
	/usr/share/qmodem/modem_scan.sh disable "$1"
	return
	fi
	# if device_path not parent of netdevice_path,then disable device path an scan again
	netdevice_path=`readlink -f /sys/class/net/$network/device/`
	device_path=`readlink -f $path`
	is_parent=`echo "$device_path" | grep -q "^$netdevice_path"`
	if [ -z "$is_parent" ] || [ ! -d "$netdevice_path" ]; then
	/usr/share/qmodem/modem_scan.sh disable "$1"
	/usr/share/qmodem/modem_scan.sh add "$path" "$slot"
	fi
	}

并且查看配置文件后发现path为完整路径不需要二次拼接

root@H29K:~# uci show qmodem
qmodem.main=main

建议修改如下,经测可正常disable无效的profile (顺便删除无效的网卡别名)

另外检查拨号log发现一直有输出 modem_dial:at port response unexpected, 但是貌似并不影响使用? 或不会明显感知
#111 修改PDP上下文序号为1时, 就无法获取到ip了, 留空时正常, 详见下述log

你好！先回复pdp相关的问题

对于大部分设备和sim卡而言，pdp index其实应该不填的。理论上cgdcont只需要填ip或者ipv6即可，然而这个项目初期是参考了另一个项目的代码。那个项目主要是为了解决ec200以及350的拨号问题，引入了pdp index这个设置项

但是我发现实际上是因为 ec200配置激活pdp的指令参数顺序和其他移远模组不一样，pdp index和enable参数调换了，导致使用通用指令pdp disable掉，而那个项目可能歪打正着 以为是pdp index掉问题，误打误撞播上号了

然而在发现这个bug的时候项目已经公开一年多了，很多模组都是指定过pdp跑的，这会导致一旦修复这个bug（移除pdp设置命令）反而会可能拨不上号，除非重置模组或手动移除之前设置过的pdp

这个项目的使用者可能是放在老家、户外甚至野外监控等应用，推送这些需要实地操作的更新可能会引发一些严重后果，而我手头的模组也不足以覆盖所有的测试，以及开发自动处理的脚步，所以就一直没有动力去修这个bug

fuck 29k这个修复 以为我没有能够复现的设备 就凭感觉写了，如果你测试能够修复 欢迎提一个pr！如果你不方便提交pr 我也可以自行修复，感谢你的建议

我正在排查 modem_dial.sh.check_ip() 我不懂驱动之类的，但或许这只是轮询问题?

应该是设置pdp index之后at返回格式不对了
