Trying to connect to Blynk using Arduino Uno and SparkFun ESP Wi Fi Shield using the code below.
I receive this error in the serial monitor, Give Blynk a Github star! => https://github.com/blynkkk/blynk-library
[675] Connecting to NETGEAR26
[1690] ESP is not responding.
Looks like it connects to my router NETGEAR26, but the the ESP is not responding. Need direction or help to troubleshoot. I have tried many different sketches but this one is the only one that connected to my router.
Thanks
Paul
