Hi Sara, Since we got Bypass working on this modem, and @jlemontu-org (whose display name doesn’t match his username :)) has a window of time today to redeploy it in the field, we opted to just roll with it, so I haven’t taken the time to try #modemLast again, but thank you for the fix (I understand about the bleeding edge!)

Thanks for the tips…[Read more]

Fix pushed.

@lemmon – most of them were deployed in the field working and stopped for no apparent reason.  I didn’t realize we’d had so many failures until Shannon dumped them on my desk the other day.

@mbarney – we’ve gone back and forth over and over about the transparent-vs-bypass issue.  My experience has generally been that the modem connects more q…[Read more]

I’m curious, were those LTE XBee3’s deployed in the field, worked properly then at some point stopped connecting to the internet? Or did you receive them and realize they wouldn’t connect upon initial testing? Just wanting to understand if this is something I need to watch out for with our LTE stations we’ve already deployed.

Thanks

Hi Sara,

I want to update you on the results of our latest testing. I noticed that there was a new release of EnviroDIY/TinyGSM, so I installed that and re-tested. Transparent mode still failed (see transparent.txt), but Bypass works. I tried flipping back and forth several times, and Transparent never worked; Bypass always did. Next, I decided…[Read more]

@shicks came over to my office yesterday with a pile of LTE XBee3’s that will no longer connect to the internet.  We’re going to buy some alternative types of modems to see if any of them are any better.

I found the issue with the help of a friend. It doesnt work with some board versions. Got it to work with esp8266 version 2.5. The only one ive tested that works but my friend told me that atleast 2 more works. Will update witch ones working!

LOL!

This is all very helpful – thank you!

I just updated TinyGSM via pio:

From https://github.com/EnviroDIY/TinyGSM
   30f09b2..5efcc5a  master     -> origin/master
Updating 30f09b2..5efcc5a

and re-tested (still in Transparent). No joy…and then Skype disconnected me from Jake’s computer, where the Mayfly is… not the ideal way to troubleshoot…[Read more]

Doh!  I’m sorry, I was confusing you with Dan who was troubleshooting issues with the UBee last week.  They’re even worse than the LTE XBee3’s.

The power isn’t your problem testing in the lab.  That seems a hair low for being connected to USB, but not concerning.  On the last bypass output that you posted from over the weekend, you did con…[Read more]

I just pushed some improvements yesterday to the EnviroDIY fork of TinyGSM that should help with the uBee.

Are you using the same program you posted earlier?  Can you post the output with debugging enabled?  (<span class="crayon-i">sensor</span><span class="crayon-sy">.</span><span class="crayon-e">setDebugStream</span><span class="crayon-sy">(</span><span class="crayon-sy">&Serial);</span> and capture the stream from the serial port monitor)  Are yo…[Read more]

The voltage levels logged during these tests were from 4.67 to 4.776V. The mayfly was powered via USB and LiPo.

I don’t know the Digi firmware version number on the XBee, but it was installed July 25, 2019. Additional background: What we’re attempting to do is to take this station and update it so that it’s more lenient on battery voltage…[Read more]

Do you have any idea what could be the issue? Thanks

I finally actually did some testing with my own board and managed to get most of the same errors you found in Bypass mode and pushed some corrections to TinyGSM.  It’s all about the issues with synchronous and asynchronous opening.  I figured out how to make it crash every time and (hopefully) how to make that not happen.  And the good news is th…[Read more]

I’m sorry.  No, I don’t think it’s an issue with the battery or the SIM.

When you were running in Transparent, the XBee3 just didn’t register an internet connection.  They just do that sometimes – refuse to acknowledge they are registered on the network.  Sometimes switching from transparent to bypass and back to transparent “magically” fixes th…[Read more]
