POSTing from Arduino via XBee Wifi on SoftwareSerial | Arduino | Forum

Hello everyone.

Like many people I've made a distributed sensor network via XB Series 2 modules, sending back to a central base unit Arduino, and now want to send this data to Thingspeak.

The base station Arduino has an XBee Wifi module running through SoftwareSerial.
The XBee is configured with the appropriate SSID, passphrase, destination ip 184.106.153.149 for thingspeak, port 80, via XCTU.

I can't successfully post the update string suggested on the Data Import/Export tab:

https://api.thingspeak.com/update?key=xxxMY KEYxxx&field1=0

After days and hours of futile searching and different attempts, I haven't found anyone addressing this scenario. I thought this setup would be quite common. I came to believe this would be the easy bit.

I can paste that update string into the address bar of my browser, and the relevant feed updates - but nothing happens when I send the same text through the XBee Wifi.

What is the format for the arduino code?

This is what I've tried:

WiFiSerial.print("https://api.thingspeak.com/update?key=xxxxxxxxxxx&field1=0")
WiFiSerial.print("POST https://api.thingspeak.com/update?key=xxxxxxxxxxx&field1=0")
WiFiSerial.print("GET https://api.thingspeak.com/update?key=xxxxxxxxxxx&field1=0")
WiFiSerial.print("POST /https://api.thingspeak.com/update?key=xxxxxxxxxxx&field1=0")
WiFiSerial.print("GET /https://api.thingspeak.com/update?key=xxxxxxxxxxx&field1=0")

I'm obviously missing something fundamental.

Thanks in advance.

Andy.
