Thank you so much for your reply. I was just getting ready to try to figure it out. I’ve been having issues with my batteries draining, so this will be a tremendous help.

Edited 6/8/19:
After some trial and error, you need to set pin 23 to LOW before transmitting. At least that’s what I could get to work with the xBee’s I’m…[Read more]

The end nodes are set to pin-sleep mode so that the Mayfly wakes them when it’s time to send data. So the Mayfly just drives a pin low (Xbee modules sleep when pin high, and wake when pin low) to wake the module, send it a line of serial text at 9600bd, and the Xbee transmits that line to the coordinator (who’s always awake), and then the May…

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]

Shannon, thank you for setting me straight. Daniel, thank you for the image.

My end goal is to have an xBee to wifi gateway. If I can get it to work, I’ll connect the ESP to TX0/RX0 and have the xBee in the socket. Right now, I’m trying to connect an ESP8266 ESP-01 to the TX1/RX1 pins. Do the TX1/RX1 pins transmit at 3.3V? I can…[Read more]

I downloaded the free version (maybe this is the issue) in an effort to view the protoshield dimensions. When I try to open the .brd file, I get the following error:

line 8, column 16: This is not an EAGLE file.

I would appreciate your insight as to what I’m doing wrong.

In my situation, ethernet is not an option. I need to go from the xBee to WiFi. Can I attach an xBee and an ESP8266 to the Mayfly? Or is there a better method?

I’ve been using the Mayfly for two years to log soil moisture levels and record it on the SD. It’s…[Read more]
