Dan started the topic MayFly Kit/Bee Adapter availability December 2019 in the forum Mayfly Data Logger 1 week ago
I noticed both the LTE Bee Adapter and the Mayfly Data Logger Starter Kit are unavailable on Amazon. Are there plans to replenish stock in the near future? Thanks.

Dan started the topic Logging interval resets every ~256 samples in the forum Mayfly Data Logger 11 months, 3 weeks ago
When powering on the MayFly running a script with a Logger object, 10 samples are recorded at 2 minute intervals, regardless of what the value of loggingIntervalMinutes is. After these 10 samples, the logger reverts to loggingIntervalMinutes.
I have additionally found that every ~256 measurements, (in my case, where I’m sampling at 15 minute…[Read more]

Thanks Sara. The modem responds with an “OK” to the “+++” in setup() but once it’s in the loop it does not respond to anything I type in the serial monitor (AT commands, +++, etc). That’s the purpose of the StreamDebugger, right?

Well, I have regressed even further. Now I can’t even get the modem to turn on. I confirm ~4.2V between pins 10 and 1 on the Xbee, so it is definitely getting power (and from the LiPo to boot) but it is no longer responding to the first initialization in e.g. logging_to_EnviroDIY.ino. Unforunately I don’t have any development board other than the…[Read more]

Thank you Shannon.
OK, I cut the trace and confirmed no continuity between BEE_Vcc and 3v3 at SJ13. Then I made a solder bridge between BEE_Vcc and LIPO. I have ~4.1V between GND and LIPO/BEE_Vcc.
The modem powers up and is evidently powered by the battery now but I still end up with the NO RESPONSE messages…

OK, looking at the GitHub issue, it looks like I may need to Solder SJ13 after all…?

I recently successfully set up a MayFly with GPRSbee radio. It works great.
I’m trying to get a second MayFly working with the Digi XBee3 LTE-M radio. This is on hologram, using a brand-new SIM card, which I understand should be possible. I’m not sure if I’m getting to that point, since even initializing the radio doesn’t seem to work 100%. I…[Read more]

Dan replied to the topic Current, best-supported cellular XBee radio for MayFly in the forum Mayfly Data Logger 1 year, 2 months ago
Sara, thanks for your thoughtful and complete response. I’ve been reading a lot of threads, and hadn’t realized the issue with Digi XBees was restricted to Hologram SIM cards. I’m using a Hologram card for now, but am not committed to it.
Is this an accurate summary of the present situation for XBee modules and MayFly?

What’s the current (Oct 2018), best-supported cellular XBee radio for use with a MayFly? It would be nice to have a US-based supplier and it seems the GPRSBee is available only from Sodaq in the Netherlands. The newer 3G and LTE XBee radios from Digi are more easily available through Mouser and Digi-Key but may or may not be fully supported on the…[Read more]
