Hi,
Now I am sending AT Commands in two ways1. through Tera Term 2. through UART ( Wifi Module Connected to my MCU via UART )Is there any other way to send AT commands ?Is it possible to send AT commands on air ???2016-02-10 11:12 PM
Hi Kumar,
using internal webserver, you can remotely execute some actions (like a local AT command from UART). But not all of them.There is no way to send AT commands OTA. You can however open a socket server, use external MCU to parse received string, detect kind of required action, and issue related AT command. Should work easily.jerry2016-02-10 11:44 PM
Hi Jerry !
I am really sorry because I couldn't follow you :( What you mean using external MCU ?my doubt is how to open the socket server at the first instance without the help of tera term ?at present I am opening the socket server using tera term by sending the command ''AT+S.SOCKD=8825'' now the port 8825 is opened and ready to listen.Is there any other way to send this command ?2016-02-10 11:53 PM
Teraterm or MCU act at the same way. The only difference is that (using teraterm) you act like an MCU.
If you want to perform a scan, for example, send ''*123#'' from the remote. You (or the MCU) parse the string, and associate ''*123#'' to an action (the scan, in this case). Now, switch back to command mode, and issue the ''AT+S.SCAN'' command. Collect the result in a buffer, switch to data mode, and send back that buffer to remote.Module was designed to be used together with an MCU. Human interaction (teraterm) is only good for evaluation purpose. In a real scenario, MCU perform the job.
