I am facing packet loss scenario with quectel-CM application when bulk transmission is done from the remote end.
Whereas if I stop using that application & instead use AT commands (AT$QCRMCALL) to setup data call, this issue is not observed.
As per my understanding quectel-CM does all control operations (APN profile etc.) over the QMI channel & then keeps polling that
interface (via GobiNetThread thread) for further events.
Can this event polling cause that above issue? Will appreciate any pointer in that context.
EM12 firmware version is 16 & my linux kernel is 4.14. I am using quectel provided Gobinet driver.
