⚫
PCI Express Base Specification Revision 3.0
compliant
⚫
Data rate up to 8 Gbps per lane
4.3.1. PCIe Operating Mode
The module supports endpoint (EP) mode and
root complex
(RC) mode. In EP mode, the module is
configured as a PCIe EP device. In RC mode, the module is configured as a PCIe root complex.
AT+QCFG="pcie/mode"
is used to set PCIe RC/EP mode.
