HI, I am trying to create a HTTPS POST request to make an API call to the Sensibo API.
I can't seem to get any response from the server.
I tried changing the code to client.connectSSL(server, 443), but did not get any response.
I tried to use the default and the modified Firmware Updater tool from http://forum.tinycircuits.com/index.php?topic=1969.msg4061#msg4061 (http://forum.tinycircuits.com/index.php?topic=1969.msg4061#msg4061), to update the SSL root certificates for connectSSL() but both tools did not work.
Both Firmware Updater showed the "Programmer not responding" error.
Help is much appreciated.
connect() function:
char server[] = "home.sensibo.com";
SerialUSB.println("\nStarting connection to server...");
// if you get a connection, report back via SerialUSB:
if (client.connect(server, 80)) {
SerialUSB.println("connected to server");
// Make a HTTP request:
client.println("POST /api/v2/pods HTTP/1.1");
client.println("Host: home.sensibo.com");
client.println("Connection: close");
client.println();
}
The connect() function returns this response this:
HTTP/1.1 301 Moved Permanently

Hello,
Did you set the wifi pins in the sensibo example? This line should always be in your setup loop when using our Wifi TinyShield:
WiFi.setPins(8,2,A3,-1);
It may help to go back to basics and get a simple WiFi connection working before adding the Sensibo API into the program. Try our getting-started example here: https://learn.tinycircuits.com/Communication/WiFi_TinyShield_Tutorial/
Let me know how that goes!
Best,
Réna

I have set the WiFi pins accordingly.
The API calls are for IoT devices in my network.
So far, I am able to make API calls using the connect() function with HTTP (not HTTPS) requests, to a Philips Hue Bridge and a WeMo smart switch, with the difference of both being accessed via a local IP address and the Sensibo API being accessed via a public IP address, hence HTTPS.
I am able to get HTTP responses using the WiFiWebClient.ino example, albeit getting the HTTP response status code 301 Moved Permanently.
For the 301 code, I believe I require SSL for the connection.
However in the WiFiSSLClient.ino example or using the connectSSL() function, even with the default "www.google.com" , there is no HTTP response output in the SerialMonitor.
All of which outputs:
Starting connection to server...
disconnecting from server.
Is it due to the SSL certificates not uploaded?
And if so, is it possible to assist me by providing a step-by-step method to perform the Firmware Update to upload to SSL certificates?
Edit: I managed to upload the SSL certs to my TinyZero, however, there is still no output.
Edit: I have resolved my issue, the issue was that in the FirmwareUpdater.ino, SerialUSB is required instead of Serial. Then uploading the SSL certs went without a problem.
Thank you! :D
