About making AT commands via QMI via PCI interface (M.2 connector) on the RM551E-GL:
Perplexity AI stated that the pcie_mhi driver combined with the quectel-qmi-proxy -d /dev/mhi_QMI0 & program will produce a /dev/tty* serial port.
I guess this might be totally incorrect. In either case, for me to try this could take me 100 hours of work and I could still reach an incorrect conclusion.
It’s great if you clarify if this is really offered and if so, how to install, build, configure, setup and use it on a recent Linux computer e.g. Debian.
For the related device RM520N-GL, in the post RM520N-GL PCIe driver and AT command interface , the poster @dooglas77 reported a problem making this function work, he wrote:
there are no virtual serial ports for executing AT commands. What is required to expose these virtual serial ports so I can run AT commands?
He did not write if he had success eventually. I’ll follow up there to ask him if he got it to work eventually.
