Using hologram with a SARA-R410M devkit on Linux

[AndrewGifft]

I’d double check from one of the Hologram employees who reply on this forum but based on:

Raspberry Pi 3 and SIM808/SIM800 Board

Just wanted to mention that we do have some support in there for a couple different Huawei modems that were popular with our customers and that we sold for a while: the E303 and the MS2131i. You are correct though in that we don’t support that specific one and there is no support in the SDK right now for a modem that uses UART instead of USB. The SDK is entirely written to only detect modems that are mounted on the USB port right now. It might be possible to reuse some of our code for a modem c…

I dont think the Hologram SDK will work with your setup. Per Reuben “The SDK is entirely written to only detect modems that are mounted on the USB port” so I dont think it searches for Compatible modems on any COM ports. Note that even though most devices interface with the computer on a USB cable they are seen as virtual COM ports. I think Reuben means something different here.

Secondly, double check you have the latest SDK, it looks like support for the R410M may have come with v0.8.0 on changelog dated 7/19 per: hologram-python/CHANGELOG.md at c1af4988be88e963096634dc10ad5c3e19053559 · hologram-io/hologram-python · GitHub

Best of luck!, and definitely wait to hear from Hologram for a definitive answer.
