ESP8226 WiFi Shield WRL-13287 Heating Up & SoftwareSerial

Wireless & IoT Wifi

Hi Sparkfun,

I got my WRL-13287 to work great with my Redboard, connecting to my MQTT Server, and publishing a counter every 15 seconds. Doing this uses 1429 bytes (69%) and anything above about 70-75% I get a warning about stability due to low memory. I have taken out EVERYTHING not needed to accomplish the above.

So I purchase a Redboard Turbo to more memory and Qwiic. I also purchased a couple of Qwiic sensors…

SparkFun GPS Dead Reckoning Breakout - NEO-M8U (Qwiic)

SparkFun Environmental Combo Breakout - CCS811/BME280 (Qwiic)

So I was unable to get the WiFi working and found the following…

viewtopic.php?f=121&t=52470

So in this forum it mentions that the ESP8226 library had to be modified to get communications. What was this modification???

I see that the above topic was closed? Why? Was there any resolution???

I plugged in my ESP8226 and while modifying my code to work with the Redboard Turbo, I checked the ESP8226 and it was EXTREMELY hot as reported in the 52470 topic. I quickly unplugged and hope I did not brick it.

When I try to compile my sketch with the new Redboard Turbo, it complains that SoftwareSerial.h can’t be found.

I thought SoftwareSerial was a thing of the past???

So I thought about buying the SparkFun Thing Plus - ESP32 WROOM.

Can I trade my Redboard Turbo for one of these.??? If so, I live in Fort Collins, CO and would like to drive to Niwot to make the switch. We can set up delivery/pickup details so that no one has to get close.

Please Help…John

Hooked up ESP8226 WiFi Shield back to my regular Redboard and it worked. So I did not brick it as feared.

The shield is working correctly, correct? But not with the Turbo?

Hi Brandon, that is correct. the ESP8226 works with the Redboard but not with the Redboard Turbo.

I should have also stated, that I needed the expanded memory of the Redboard Turbo to do my MQTT stuff.

Thanks…John
