Just as refresh this is my data while working with a prototype SDI-12 level shifter.

@james_nz my process is to stage systems in an accessible context to check the reliability of the systems. This comes from the school of hard knocks working with embedded processors like the Mayfly.
IMHO while ModularSensors software has some fantastic classes to be able to access the instruments and also to push to cloud locations, Ar…[Read more]

@shicks, thanks for your help anyway Shannon. @aufdenkampe, any insight on the code above would be greatly appreciated.
@neilh20, yes all setups are the same. Some work fine, others have issues with dropping out. I have spare Mayflies and a spare CTD, but no spare turbidity sensor. Did you ever end up producing your Mayfly wings for the 0.5…[Read more]

Hi Shannon,
I replaced the battery with a new one when I started this process of trying to revive the Mayfly. The original battery may have still been good, but it was several years old and the unit has been sitting for a year or so – so I figured it would be best to start fresh with a new battery.
The board doesn’t have a modem so time…[Read more]

If there’s a CR1220 watch battery installed in the battery slot on the Mayfly (with sufficient voltage) then the RS3231 RTC will still be alive and continuing to think it’s whatever time it thinks it is. However if the board has been sitting in storage for awhile and not attached to a main Lipo battery, it’s likely that the CR1220 is dead and…[Read more]

Hi Shannon,
Thanks for the info. I downloaded the drivers at the link provided and restarted my computer but still no additional ports appear when Arduino is open and the mayfly is connected, turned on.
I’ve ordered a new micro usb/usb-c data cable that should be arriving today. This will let me check on 2 variables; 1) it will allow me to h…[Read more]

@James_NZ – are all your setups the same?.
Have you got a spare setup that can be debugged in a local setting? (office with terminal connected)
I have a similar setup with an RS485 and SDI-12 on one system – but I maintain a test system to verify it before I deploy it.

I’m not familiar with the code regarding the complex loop since it’s not something I’ve ever used, and I’ve also not used one of those modbus wings, so I think Anthony or Neil will need to be the ones to help with this issue.

James_NZ replied to the topic Hydros CTD-10 Regularly Dropping Out (-9999) in the forum Environmental Sensors 2 years, 8 months ago
Hi @shicks. I’m just wondering if you saw anything in the code above that might be causing this problem?
Regards,
James

If your Mac isn’t seeing the Mayfly as a USB device in your computer OS list of current devices, then you need to install the FTDI drivers from the device website at https://ftdichip.com/drivers/vcp-drivers/
Mac and Windows 10 should automatically install those drivers whenever a Mayfly is connected to a computer for the first time, but sometimes…[Read more]

DaveG replied to the topic pc and Mac unable to communicate with mayfly ver. 0.5b in the forum Mayfly Data Logger 2 years, 8 months ago
Thanks. I’ve done everything the video shows already, but there is no additional port popping up when I turn on the mayfly.

Here’s a video of the process of installing the driver:

I’ve tried unsuccessfully to download and install drivers from the tutorial – some of the links were bad and then if I could download a driver, the installation was blocked b/c extension issue.
This is way over my head and I am so grateful for your time and help but I feel like I am just going in a circle

fisherba replied to the topic pc and Mac unable to communicate with mayfly ver. 0.5b in the forum Mayfly Data Logger 2 years, 8 months ago
Nope. The instructions here: https://www.envirodiy.org/mayfly/software/ say to not use 2.0. I don’t use the Arduino IDE for anything but getting people started. But the tutorial I sent will lead you to this Mayfly driver and through a whole set of steps that will get you up and running. It may look TLDR, but I think it will help.

DaveG replied to the topic pc and Mac unable to communicate with mayfly ver. 0.5b in the forum Mayfly Data Logger 2 years, 8 months ago
ok, I just downloaded Arduino yesterday. Should I maybe try the beta version for the latest update?
-
fisherba replied to the topic pc and Mac unable to communicate with mayfly ver. 0.5b in the forum Mayfly Data Logger 2 years, 8 months ago
If the usb port doesn’t exist, then the most probably cause is that the driver is not installed or not valid/current.

DaveG replied to the topic pc and Mac unable to communicate with mayfly ver. 0.5b in the forum Mayfly Data Logger 2 years, 8 months ago
I don’t have any other ports as options to select. The only other thing it says is “serial ports” but that is greyed out and not able to be selected.
