As per those suggestions, I have added the Adafruit IO SSL Certificate to the WINC1500 board successfully. But trying to run the example, Arduino->Examples->Adafruit_IO_Arduino->adafruitIO_00_publish with "#define USE_WINC1500" in config.h fails to connect.
I turned on AIO debugging in AdafruitIO_Definitions.h as follows:
Code: Select all
// Uncomment/comment to turn on/off debug output messages.
#define AIO_DEBUG
// Uncomment/comment to turn on/off error output
#define AIO_ERROR
Code: Select all
Serial.print("Connecting to Adafruit IO");
////////// Test of WiFi setpins for WINC1500
int8_t cs = 10;
int8_t irq = 7;
int8_t rst = 5;
int8_t en = -1;
WiFi.setPins(cs, irq, rst, en);
// connect to io.adafruit.com
io.connect();
