I think the main problem right now is that the modem data session lasts about the whole length of the logging interval. The cell modem seems to stay on and connected too much.

OK, I see, thank you, that makes sense. I should be able to extend the time of >3.65V by increasing my logging interval from 5 to 30 min. I’ll keep that ‘attempt to re-send data’ project in mind as I gain experience and availability.

Dave,

I bought the PulseLarson W3554B0140 RF ANT 829MHZ/2.2GHZ PCB TRACE (https://www.digikey.com/products/en?keywords=553-2574-ND) and I’m pretty sure it works. It looks like the one that comes with the Development kit (https://www.digi.com/products/models/xk3-c-n1-ut-e).

mdean,

I want to try those things but don’t have enough experience yet to know exactly how. When you reference TinyGSM (increasing the timeout time) what exactly do you mean by TinyGSM? And defining the modem serial at 9600 is understandable except I don’t see where to do that (in my logging_to_EnviroDIY sketch or in a different sketch that sets up the modem)?

I feel like I’m close.
Thanks for your input.

Cal,

I have the hardware:

Mayfly Datalogger v0.5b
Digi XBee3 Cellular Lte-M/NB-Iot – XB3-C-A2-UT-001
No antenna – 3 bars of AT&T on my iphone
Soldered SJ13 and cut trace BEE-Vcc to 3v3 – 4.19V between Bee pins 1 and 10
3.7v Lipo battery
Solar panel from mayfly startup kit
USB to Windows PC – XCTU installed but not implemented
Hologram SIM activated

Software is:

logging_to_EnviroDIY with lines 53 (loggername), 54 (file name), 58 (registration token) 59 (sampling feature), 67 (BEE_TYPE = “gprs”), 68 (APN = “hologram”), and 321 (onboard_battery multiplier * 4.7 *) customized

and I’m getting this message from the Arduino 1.8.8 Serial Monitor:

09:44:27.286 -> — Request —
09:44:27.286 -> https://data.envirodiy.org/api/data-stream/

09:45:08.974 ->
09:45:08.974 -> Request to data.envirodiy.org timed out, no response from server or insufficient signal to send message.

I’ve tried multiple iterations of connecting the battery to the board.
My hologram dashboard shows the device state is live but there is no usage.
My site on Monitor My Watershed shows ‘Sensors have no data’.

I have a 900Mhz radio network setup here in the Minneapolis MN and I know those radios (RF450) need individualized configurations and I haven’t done that type of thing to the XBee3 yet.

I would like to get this XBee3 connected and configured and get my data logging to the https://data.envirodiy.org/api/data-stream/ server.

How can I fix this?
