Unfortunately, it is not possible to update 32 fields across four channels in one command. You can use four commands with the same syntax that you show above to update four channels. I would put a small delay of 10-100 ms between each call to avoid a burden on the server. Dont forget to use the correct API key for each channel.

If you absolutely have to update all 32 values in a single call, it is possible to pack multiple values into one field, but then you will need to unpack them again later. For example, you could write

...?api_key=xxxxxxxxxxxxxxxx&field1=value1,value2,value3...value32

Then when you read the values from ThingSpeak, you will need to parse the date for the comma. Also, in this mode the standard field plots wont show your data, but you could write a MATLAB visualization that reads the values and parses them, and then displays them.

Hi Shyam,

Each channel in ThingSpeak has 8 fields, accommodating 8 sensors’ data. You can use multiple channels to accommodate the data of 32 sensors.

but mam at a time 32 field is not updated..

how to update 32 field at the same itime.

i used this line for updating 8 field

String str="GET https://api.thingspeak.com/update?api_key=X9NE6XWDIYOO71WI&field1=" + String(temp)+" &field2= " +String(temp1)+" &field3=" +String(temp2)+"&field4=" + String(temp3)+" &field5= " +String(temp4)+" &field6=" +String(temp5)+ "&field7=" + String(temp6)+" &field8= " +String(temp7)

for updation of 32 field what i can do

[Pujitha Narra]

The command updates a channel with api_key=X9NE6XWDIYOO71WI. You can create 3 more channels and add commands for each of the channels.
