@jfrog, thank you for your swift reply. I’ve tried to get it to work using ethernet also, according to the manual the following AT commands are used to set the module into WLAN/Ethernet function mode:
AT+QCFG=“data_interface”,1,0: switch the module to PCIe interface.
AT+QCFG=“pcie/mode”,1: set the module to PCIe RC mode.
AT+QETH=“eth_driver”,“R8168”,1: load the driver for RTL8111H TE-A.
AT+QETH=“eth_at”,“enable”: enable the driver.
I’ve followed the steps and entered in the commands above, the green light on the RTL8111H TE-A blinks. How can I send AT commands via the ethernet now? I’ve used PuTTY to send AT commands using telnet, to the given IP address at port 1555 (from RM502Q-AE and at+qeth="eth_at"), but the connection was refused.
Additionally, the RG520N&RG5x0F&RM5x0N Series AT Commands Manual says “The main UART port and two USB ports (USB modem port and USB AT port) support AT command communication and data transfer”, does this mean I can use the microUSB port? Any help would be appreciated.
