The new sim7080 is plugged directly into the Mayfly 0.5b.

Current status of my problem; I am using the 0.5 Mayfly board and have changed to appropite line from 18 to -1 and I get compile errors related to NeosWSerial.ccp.  I have updated all my libraries and still get the same error.

If I comment out the lib entry for NeoSWSerial the sketch compiles but when loaded the console output appears normal but the simcon board doesn’t come on so I assume the NeoSWSerial is needed and the program doesn’t default to another SWSerial function.

Help!

Hi Sara-

I spelled your handle wrong so maybe you didn’t see this.  Do yo need more details?

I observed the same issue on one of my sensor stations with last data on Dec 7 at 12:55. I have 4G modems and was working fine till then.  I am located in elverson Pa.  I thought it was a modem failure which Shannon has had a bunch of.  Maybe the Amazon cloud server problem.

I just tried this with Safari on my iMac and the scroll works to change scale so must be a Chrome problem which I typically use.  I have Chrome Version 89.0.4389.82 (Official Build) (x86_64)

My problem is that GMI_EC1 has conductivity spikes up to 900,ooo µS. The TSA chart auto scales to that level.  If I hover over EC axis and left click I can shift the scale location but I want to hover around zero and expand the scale so the all the lower EC readings are displayed.  I could do this a few weeks ago and my mouse wheel is working on other apps.  I am in my office with a iMac using Chrome.  No mouse wheel but its touch sensitive – same result.

If you look at GMI_EC1 you will see large spike around 2/19/2021 A few weeks ago I was able to expand the scale around zero to see the lower values of EC now I can’t.  If I pick dates 2/22/21 to 3/14/21 I see the lower EC spikes (probably road salt from the service plaza) so the auto scaling works but I can’t scale manually.

Try it and let me know what you observe.  I have tried on different platforms and browsers and same problem.

Thanks

I noticed this week that the TSA charts can not be scaled with the mouse scroll button but they can be shifted.  Something changed since I was able to scale and move any of the displayed parameters.

I couldn’t find this issue in any other threads so I bring it up here.  Perhaps there was a recent update and that feature got broken?

Couple of clarifications:

• The discharge is a fixed load of 22Ω so ohm’s law works!
• My question is why is the Mayfly station drawing less and less current as it approaches 3.3 Volts?  Yet the 4G modems continue to work and upload the data.
• I believe that Shannon said that some older sd cards tend to cause current draw during sleep mode.  Maybe this is what is happening.
• Matt- I am interested in your coulomb counter?  Where can I get one or is it home brew?
• I have learned that not all Li-ion batteries are equal in terms of stated Ah capacity.  I bought some from Amazon rated at 4.5 AH yet they were less than half the size of the 2.5 Ah batteries I got from Adafruit!  And the JST connector polarity was reversed!

Cheers

I am using the same hardware with my Low Cost EC stations   which is set up for UART mode but I have since upgraded to I2C mode when I added the 2G modems.  I am using the sensorex probe for the EZO EC which has an integral RTD which I read thru the analog input.  I think its only about a $30 premium for the the RTD option.  Maybe there are some ideas in my blog that will help.
