Method and device for supporting hot plug of SIM card, wireless internet access equipment and medium

Abstract

The invention relates to a method and a device for supporting hot plug of an SIM card, wireless internet access equipment and a medium. The method comprises the following steps: when the SIM card is hot-plugged, the SIM card is not hot-plugged. When it is detected that the GPIO1 pin is changed from a low level to a high level and from the high level to the low level in a predetermined time, setting the SIM card in-place mark from 1 to 0 and from 1 to 1 in the predetermined time, and resetting the LTE module by lowering an RST signal connected to the LTE module by the CPU; when the LTE module is reset, the LTE module is controlled to normally use the SIM card until it is detected that the GPIO1 level becomes low again and it is judged that the SIM card is in place again in the SIM card slot. The invention provides a method for supporting hot plug of the SIM card and not needing to restart the reset single board, which can realize that wireless internet access equipment supports the hotplug of the SIM card, effectively protects the SIM card, prevents the SIM card from being burnt out, does not need to restart the reset single board, accelerates the wireless internet access efficiency and brings inconvenience to a user.

Description

technical field [0001] The present application relates to the technical field of wireless Internet access equipment, in particular to a method and device for supporting SIM card hot swapping, wireless Internet access equipment, and a readable storage medium. Background technique [0002] It is becoming more and more common to use wireless devices to surf the Internet. There are generally wireless network cards and LTE4G modules that support wireless Internet access, and most of them are plugged into computers with USB for use. The LTE 4G module requires the support of a SIM card (mobile phone card). Generally, a SIM card slot is provided on the entire module for use. [0003] At present, there are many LTE modules widely used in IoT devices, such as automobiles, security, monitoring, forest fire prevention and so on. The biggest thing they have in common is that the LTE module and the device are integrated, and it is difficult to disassemble, unlike the hot-swappable USB o...
