ESPWiFi Shield - can't send HTTPS requests
Posted: Tue Aug 03, 2021 11:18 pmHi,
I just bought a Cytron ESPWiFi Shield (2.0) and I intend to use it to upload sensor data to Google Sheets, so I tried out the Google Form HTTPS example sketch as well as the HTTPSClient example sketch.
When I check Serial Monitor from the Google Form sketch (making sure to set my own Wifi SSID and password), the output (after it displays the IP address) is as follows:
23:11:17.953 -> Connecting to docs.google.com
23:11:20.792 -> Failed to connect to server.
I tried updating the firmware following the instructions in section 8 of the manual, but no change after that.
Here's the output from Serial Monitor from the HTTPS Client sketch:
23:15:46.062 -> Connecting to api.github.com
23:15:47.600 -> requesting URL: /repos/esp8266/Arduino/commits/master/status
23:15:48.766 -> request sent
23:16:19.085 -> Timeout
Based on the output from both, it seems like the shield is not able to receive a response from servers after making a HTTPS request. Am I missing a step in setting up the shield, or do I need to do something else to get it to work? I see in the Google Form results that people have successfully connected to it even today, so I am hoping there's some workaround or solution for this issue I'm facing.
