I have previously used several Reach M+ modules with Asix AX88772B based USB to Ethernet adapter used to establish network connection via Ethernet cable (exact assembly being Reach M+ connected with USB OTG cable to USB to Ethernet adapter and the adapter connected to network router with Ethernet cable). This configuration worked flawlessly and plug-n-play.
Now I got my hands on to some new Reach M2 modules and tested the same USB to Ethernet adapter with it. Didn’t work. Reach M2 could not use the said USB to Ethernet adapter to establish network connection. Is this because Reach M2 lacks the driver for the said adapter but M+ has it? Or is this issue related to some other difference between Reach M+ and M2 modules?
For example this thought crossed my mind: Does M2 still support USB OTG? The device documentation (https://docs.emlid.com/reachm2/) states that USB OTG cable would be supplied with the module, but the ones I received did not have USB OTG cable with them. M2 documentation further describes use cases where USB OTG cable is used but the fact that the cable was missing from the shipment made me doubt the presence of USB OTG support.
If the issue is related to a missing driver, then is it possible to install the driver to M2? If yes, then can anyone point me towards driver installation instructions.
This topic was already touched by this post: Reach M2 and ethernet adapter (post was already closed, so I could not continue it). In this post the suggested solution was a “feature request” for Emlid. I am looking for a solution that I could implement by myself without the need for waiting future software updates. The reason for uncompromising need for Ethernet connection is that Reach M2 modules are used in environment where lots of electromagnetic interface is present and wireless connections are therefore unreliable. Wired serial connection is also not an option since I need to access Reachview control panel occasionally, which can only happen through network connection.
Thanks in advance for helping me with this issue!
