Hi, I’ve got some issues with my RM500U-CN module…
a) Using the AT+QCFG=“usbmode”,host command I’ve now lost USB connection to the module (previously it was connecting via both USB and PCIe, but I lost the USB connection BUT still had USB ports - and the AT command port obviously. When I issued the host command above I lost all the ports! Please how can I restore the USB ports…
When I power it up, a port called - SPRD U2S Diag (COMx) appears briefly, but then disappears…
b) When I issue the AT+QCFG=? command (earlier, when I had an AT port!) I get a long list of available commands. Some I can guess at but none appear in the AT command manuals. Please can someone explain what these all do… The are listed below!
Thanks…
