I have an Uno Wifi v2 board and I'm using WiFiNINA to connect to an API on the Internet. I can perform GET requests to the API without any issues but when I attempt to perform PUT requests I get errors.
connected to server
HTTP/1.1 400 Bad Request
Server: awselb/2.0

Here is all of the code:
/*
This example puts data to a secure API endpoint

#include <SPI.h>

char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS;
char server[] = SERVER;
WiFiSSLClient client;
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// check for the WiFi module:
if (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
while (true);
}
String fv = WiFi.firmwareVersion();
if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
Serial.println("Please upgrade the firmware");
}
// attempt to connect to WiFi network:
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:

delay(10000);
}
Serial.println("Connected to wifi");
printWiFiStatus();
Serial.println("\nStarting connection to server...");
if (client.connect(server, 443)) {
Serial.println("connected to server");
client.println("Content-Type: application/json");
client.println("User-Agent: ArduinoWiFi/1.1");
client.println("PUT / HTTP/1.1");
client.println('{"id":"78918", "name":"Pizza", "price":"12.45"}');
client.println("Connection: close");
client.println();
}
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
while (client.available()) {
char c = client.read();
Serial.write(c);
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting from server.");
client.stop();
// do nothing forevermore:
while (true);
}
}
void printWiFiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your board's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
I need Content-Type to change to application/json and I need the payload sent with the request. How can I do this with the WifiNina library?
