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 syncing can’t happen that way.  It isn’t a feature we’re likely to add to the Mayfly, either.

Hopefully I’ll get this unit to connect to a pc, if not then we’ll have to go the Adafruit way.

thanks again for your time and help.

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 have a new data cable with all new pins, 2) it will allow me to bypass the apple dongle that converts the standard usb connection to a usb-c.

Additionally, I’ll try connecting it to a pc this afternoon following the tutorials that Beth sent.  If none of these steps work, then I’ll get the “friend” from Adafruit.

Finally, the mayfly was previously used for monitoring CTD and turbidity.  I will be using it for the same purposes, just at a different location.  The sketch should be on the Mayfly already but without accurate time/date information, the data doesn’t have much value – and I can’t correct the time and date without making a connection to the computer, correct?

Thanks again for your time and help.

Thanks.  I’ve done everything the video shows already, but there is no additional port popping up when I turn on the mayfly.

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

ok, I just downloaded Arduino yesterday.  Should I maybe try the beta version for the latest update?

I just downloaded Arduino 2.0 and it is still only showing the bluetooth port… see image

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.

[DaveG]

Understood.  I added Arduino to programs that can open ports/get past firewall on the Mac but is still only showing the same bluetooth port info for the Mayfly.  I just did a quick search online and other folks have been having this problem too.

Dunnoh.

so I thought I’d try it with the micro sd card removed… then I captured the following images of the Arduino program and the serial monitor – but still no port prompt, although mayfly appears to be “seen”

I was not able to get Blink uploaded – even at the baud rate recommended.  I verified it but still got the same “not in sync” error message as above

The serial monitor does not show any text but the boards manager shows Mayfly 1284p.

I’ve tried 3 different micro usb cables and none of them have had the Mac ask for a port for the Mayfly

[DaveG]

I’m sorry, I’m not getting it to work.  It seems like I am missing something simple but I’m still just getting the same error message as before.  I tried doing the blink tutorial and it didn’t work – serial monitor didn’t show anything even when switched to 9600 baud – and still had the same error message.

Then I followed the steps above and am still not getting prompted about selecting any port when in the serial monitor.

who wants to do the kicking now, huh? 😉
