      Thanks for the info Shannon.  I will check out the GPRSbee and sd card to see if they are the cause of the 2.4 mA draw when in sleep mode.  I’ll try a new Mayfly board next.

        I checked my GMI_EC5 station that I mentioned above that was not keeping up and I measured about 2.4 mA current draw when the mayfly is in sleep mode.  I thought it should be close to zero when in sleep mode.

        Any thoughts Shannon?

          I have the same issue.  I have my LEC stations (GMI_ECxx) running with 2G cell service and I did have one station that the solar charge chip failed and caused battery to drop below the 3.55  volt threshold for upload.  However GMI_EC5 seems to be getting a charge during the day but is still not keeping up.  I attached a screen from MMW TSA and you can see the drop-off in voltage on this sensor station vs the others.  I also noticed a general drop off which I presume is amount of daylight.  I am using the 2.5 AH batteries.  I plan to check current draw to see if it is abnormal or caused by poor cell service.

            I checked Amazon and finally discovered that “envirodiy mayfly protoshield” works for a search.  Did not have envirodiy in my search query.

            I just bought the last one so guess time to restock

                I just checked Amazon and no Protoshields showing.  I guess shipment processing isn’t one day turnaround!

                  Any updates on the availability of the Protosheilds?

                    Thanks.  I am using the FTDI port and wiggled some plugs, etc and now is loading ok.  I assume when I was getting that error the mayfly was plugged in and turned on because when I attempt to load with the pwr switch turned off I get the following error:

                    Uploading .pio\build\mayfly\firmware.hex
                    avrdude: ser_open(): can’t open device “\\.\COM4”: Access is denied.
                    avrdude done.  Thank you.
                    *** [upload] Error 1
                    I guess a bad connection somewhere.

                      Hi Sara  @srgdamiano

                      I haven’t used PIO for several months but in preparation for the transition from 2G to 4G I launched PIO this week and it apparently did an upgrade and now my code won’t load.

                      I get the following error:

                      avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

                      PIO is currently core 4.3.4 and home 3.2.3

                      Any help on this would be appreciated.

                      Thanks

                        @heather

                        Since it’s not a MMW issue should I move my technical questions back to my original post on “infrastructure and equipment” forum?
