has anyone tested Fibocom SDX75 - FM190W-GL and the Quectel SDX75 - RM551E-GL with the GL-M2?
We have not tested these two modules.
It can be determined that Fibocom does not be supported, as the GL firmware is only merge the Quectel module driver.
The RM551E probably available, but we cannot guarantee that it is completely available.
