Greg,
We never revisited the issue and instead just gave the address to the CS-215 via a CS logger. I know that our team installed an ATMOS-14 at the site, and got around power issues by just powering the sensors separately from the Mayfly board by using DIN rails. It really seems that the different power requirements between the board and the…[Read more]

Oops. Sorry. I’d typed that and didn’t see your response. But yes, slowing down the ESP8266 is the way to go if you want to make sure everything is heard correctly.
Sara Damiano replied to the topic ESP8266 in the forum Mayfly Data Logger 2 days, 22 hours ago
Yes, I’ve had problems with the Mayfly receiving data at 115200. The Mayfly is only running at 8MHz and Atmel says the error rate at that baud and crystal combination is 8.5%. The error is a much bigger problem on the receiving end than the sending end. So the serial port monitor and the ESP8266 understand what the Mayfly is saying at 115200,…[Read more]

SOLUTION:
I changed the default baud rate on the ESP8266 from 115200 to 9600 and things started working. The AT command I used was AT+UART_DEF=9600,8,1,0,0
Here is where I found this command:

Just curious why the ESP8266 wasn’t working at 115200?…[Read more]

My error was indeed in how I downloaded the files. Shannon, thank you for setting me straight. Daniel, thank you for the image.

Dave,
Just curious if you ever revisited this issue over the winter? I am having the exact same issue with a Viasala WXT530 and YSI EXO. I did find a post where I guy successfully got his WXT530 to work back in 2017 (https://hankpai.weebly.com/sandbox/arduino-data-logger-vaisala-some-code). We are powering the devices with 9V and able to change…[Read more]
