A6 Ai-thinker and thingspeak

Hello - I would like to send data to a thingspeak channel through an A6 AI-thinker board. The product will be in a remote location with no WIFI options. I think thingspeak can only accept data through http or tcp and have read http is a better option. That said, the only AT commands I can find and have ever used with the A6 are for sms texts. I cannot find the other commands for the chip and I do not think thinkspeak will take text messages.

Is the A6 the best choice for this? Is thingspeaks the best or at least a good choice for this? Is there a better way to communicate with thingspeak even if a different board is needed?
