What is the possibility of emulating the same AT commands that the USR232-T uses? They use AT+(command), very similar to the existing ESP8266 firmware. I have been able to connect and see our server. However, the USR232-T gets in and out of command mode using +++. When in pass through mode, data is sent via TCP or UDP, sending the packet after a timeout (settable by the user). The incoming data does not have a header like the ESP8266's +IPD... it's like the CIPMODE=1.
So, I would like to know the following:
Is actually at FULL list of the AT commands?
Is there a passthru mode where the TCP outgoing data can be sent by just sending data over the UART and receiving data also over the UART without having to use the CIPSEND function?
Is there a AT+WPS command or some way to invoke WPS?
If this is all possible, we will dump our PO with USR and purchase these.
If someone from this company can PM me, I would appreciate it.
Rather than post to a general support forum, if you are looking to contact Espressif with business opportunites, I'd suggest contacting them directly see the following:
For your question though, it seems like the AT command processor can be augmented and overridden with the "AT APIs" documented in the Section 5 of the latest SDK. These APIs allude to the ability to replace the inputs and outputs of the existing AT commands with your own variants and even extend the command set.
The AT command processor appears to be "just a" application that is deployed to the device. What that means is that, should you need, you can write your own.
Hope this helps,
