We have 1 site that resumed uploading data at 12/8/2021 14:45 ET, with no known intervention.

5 sites are uploading after we restarted them, and 18 sites that have not reported since the cutover to the new server.

We tried the Hologram SIM pause idea on one station, but it had no effect, which isn’t too surprising.

@aufdenkampe, please keep us informed about the timing of the temporary shutdown of the old server. Thanks for your efforts.

Thanks @heather, and @aufdenkampe, that does makes sense, with the symptoms we’re seeing. Good to know that the data are not being lost in the interim.

Shutting down the old server temporarily sounds like a good idea; all of our devices are on a 15-minute sampling period, so 20+ minutes should cause at least one failed message from the device,…[Read more]

oof… what a day to release onto AWS! 🙂 https://techcrunch.com/2021/12/07/amazon-web-services-went-down-and-took-a-bunch-of-the-internet-with-it/

Nonetheless, happy to hear of this milestone for MMW!

FWIW, I asked SIMCom about their Verizon certification, and this is their reply:

We are in the process of getting the certification.  All testing has been completed and we are just needing to schedule and official drive test with Verizon.  After this we expect to have certification shortly after.  I am estimating we will have it completed late De…

Ok, that’s very interesting. It sounds like the LTEBee with a Hologram SIM has been using what it sees as the ‘best’ carrier for a given connection. The Digi modems would never do that for us in areas where Verizon was the only viable option, so we had to get Verizon-branded SIMs for those cases.

Hmm, so maybe no one has tried Verizon with the new modem yet. SIMCom claims that chip supports Verizon, but (suspiciously?) they don’t have a Verizon Certification document available for download, as they do for other carriers. And they list all their supposedly supported carriers under a heading labeled “Certifications(plan)”, which makes me…[Read more]

Got it – thanks! I had the USB DIP switch off. I misinterpreted the specs sheet about the function of the switch, thinking it only disabled the LED, not the port. Is there a power penalty if I leave the USB switch on for a field deployment? The spec suggests that there is, but the USB LED won’t be lit in that case.

Ah, that helps. Thanks Shannon and Neil!

When I connected my first v1 Mayfly last week, my laptop (Win10) didn’t recognize it. I manually installed the VCP drivers for CP210x from SiLabs, and then it worked. Uploaded code (using PlatformIO) to the board, and all was well. I set it aside for the weekend, and today I can’t get Windows to recognize the Mayfly. Windows Device Manager’s list…[Read more]

I have a couple of related questions as we prepare to integrate v1.0 boards into our new deployments, while also keeping our existing 0.5b installations operating for as long as possible.

1. Will Hologram SIMs work with the new EnviroDIY LTE Bee modem? I recall seeing a discussion that it was under test, but can’t seem to find that now.

Thanks for the quick reply, Shannon. I was able to get the cables and the adapter all working, following your instructions.

Thank you.
