Airplane Mode; Communication Interface With The Host - Quectel RM510Q-GL Hardware Design

The module and the host will wake up in the following conditions:
⚫
Sending data to the module through USB will wake up the module.
⚫
When the module has a URC to report, it will send remote wake-up signals via USB bus to wake up
the host.

3.1.2. Airplane Mode

The module provides a W_DISABLE1# pin to disable or enable airplane mode through hardware
operation. See Chapter 4.5.1 for more details

3.2. Communication Interface with the Host

The module supports to communicate through both USB and PCIe interfaces, respectively referring to the
USB mode and the PCIe mode as described below:
USB Mode
⚫
Supports all USB 2.0/3.1 features
⚫
Supports MBIM/QMI/QRTR/AT
⚫
Communication can be switched to PCIe mode by AT command
USB is the default communication interface between the module and the host. To use PCIe interface for
the communication between a host, an AT command under USB mode can be used. For more details
about the AT command, see document [5].
It is suggested that USB 2.0 interface be reserved for firmware upgrade.
USB-AT-based PCIe Mode
⚫
Supports MBIM/QMI/QRTR/AT
⚫
Communication can be switched back to USB mode by AT command
When the module works at the USB-AT-based (switched from USB mode by AT command) PCIe mode, it
supports MBIM/QMI/QRTR/AT, and can be switched back to USB mode by AT command. But the
firmware upgrade via PCIe interface is not supported, so USB 2.0 interface must be reserved for the
firmware upgrade.
eFuse-based PCIe Mode
⚫
Supports MBIM/QMI/QRTR/AT
⚫
Supports Non-X86 systems and X86 system (supports BIOS PCIe early initial)
