Kevin and David, thanks for posting these issues with the MaxSonar. David, thanks also for the photos!
I’ve also had funkiness with my Maxbotix deployments this summer when using the EnviroDIY ModularSensors library. For me it just seemed like it was repeating the last values.
David, thanks for showing everyone that quick fix and for helping me…[Read more]
At least I bought the MayFly Datalogger via ebay. The problem is, that there seems to be no bootloader burnt in. I get the message: “avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x30” or similar.
Please give me a hint to overcome this problem.
Best Regards Wopo
If anyone could shed some light on which AT commands we’re either using incorrectly or missing altogether, we could greatly appreciate any assistance you can offer. I’ve posted before re: 3G FONA but we’ve run across a new problem. We’ve been successfully using the 2G FONA 808 cellular modem with a Ting 2G Sim card from Adafruit here in…[Read more]

Thanks for your help…we’ve now been able to successfully register the FONA and ping the internet. We’re still not able to post to the internet though. I’m going to going to make anohter separate post for this question in the hope that others will also see it since it’s a new question.
Thanks again…perhaps you can shed some light…[Read more]
I have an update. I think the problem comes from the reading the sensor with SoftwareSerial_ExInts. There is data left in the read buffer after the read. I’m not sure if this is a real fix, but it seems to work. There is a section of code in MaxBotixSonar.cpp that reads the six header lines from the sensor, after the power is turned on. I changed…[Read more]
Dave replied to the topic Campbell Scientific CS-215 SDI-12 communication issues w/ Mayfly in the forum Mayfly Data Logger 3 weeks, 5 days ago
Just to loop back – we were in touch with Campbell and their suggestion was also along the lines of the 3.5V voltage requirement. In the meantime, we picked up a Meter Group (formerly Decagon) ATMOS-14 sensor which collects temp/RH/VP and it worked perfectly. Since we only had to install one, we just went with that.
We’ll try to figure…[Read more]
Beth – success! Problem fixed. Board not fried. The “wicked hard to push in” really helped – I, ah, “insisted” that the battery get seated oriented as in the picture, and now everything works. Thank you for helping me through this. -Dave
I am also having a similar issue with the MB7989 with MB7955 and EnviroDIY Mayfly. My sensor was deployed for four days, and when I went back to check on it and swap out an SD card, when it turned back on, it would only read a distance of 7389, regardless of the actual distance. I am also interested in any ideas as to how to fix this issue.
Hi Dave, the orientation in your photo is correct (and that’s the correct way demonstrated in the thread you linked), so I’m a little bit confused about how yours could be fried. It’s possible that the battery isn’t contacting properly. My experience has been that they are wicked hard to push in (because the early versions weren’t tight enough),…[Read more]
You’re right, apparently my RTC is fried since it will not hold the time/date. This is very frustrating, as I followed the RTC battery installation instructions on this forum at RTC battery installation instructions.
Can I get my RTC fixed, or do I need to throw away a brand new Mayfly? -Dave
