I want to send acceleration data from a mobile phone sensor to ThingSpeak. Error: URL is incorrectly formed, or the requested feature is not supported in this version of ThingSpeak.
[acc, tacc] = accellog(m);
xAcc = acc(:,1);
yAcc = acc(:,2);
zAcc = acc(:,3);
InitialTime = datetime(m.InitialTimestamp,'InputFormat','dd-MMM-yyyy HH:mm:ss.SSS');
AccelTime = InitialTime + seconds(tacc);
channelID = XXXXX;
writeKey = XXXXXXXXXX;
tStamps = AccelTime;
data=[xAcc,yAcc,zAcc];
thingSpeakWrite(channelID,data,'TimeStamp',tStamps,'WriteKey',writeKey)

Thingspeak can only accept data sampled at 1hz or lower frequency. That is, tStamps should be at least 1s apart. My initial guess is that your accelerometer data is sampled at a much higher rate.

I want to update the accelerometer data on ThingSpeak every 1 second.

That is possible.
If you have an unstable or slow internet connection, it might be that the data you send from your device does not reach the servers exactly 1s apart. You might want to add a 5-10% buffer to factor in network latencies.
