Re: 【ESP32-C3】 AT

I don't have answers to your questions but wanted to check to see if you were able to find out anything else. I have noticed similar operation with the hostname command when using auto-connect. So, I have had to disable auto-connect and set the hostname prior to the connecting to the wireless networ...

ESP32 AT Commands Binary Data

Hi, I'm using the esp32-WROOM wifi module running AT binary version 2.2.0.0. I have a web server using the AT+CIPSERVER=1,80 command to allow clients to connect. I am able to receive data (+IPD) and process incoming web requests (GET and POST). I can send web pages as ASCII strings using the AT+CIPS...

Listening for UDP Packets on Port

Hi, I am running the AT binary on my esp32 board. Once I connect to a network I need to be able to receive UDP packets on a specific port (81). I also need to be able to send response packets as well. I have tried to start a server with the command AT+CIPSERVER=1,81 However, I am not able to see any...

Initial SSID+PWD Configuration

Hi, I am using the prebuilt, released AT command binary on my esp32 board. I have seen videos posted about the esp32 going into AP mode to allow for connecting and then setting the initial SSID+PWD via a web site, however, I am not able to do this using the AT binary. I am wondering if this function...

Re: Adding Wifi to Existing Product

Hi, I am planning on using the ESP32 in AT command mode since we do not have enough hardware interface modules (SPI, etc.) to support any other modes such as ESP-hosted that was previously suggested. (I think I can try hosted on a future next-gen product). I have the ESP32-DevKitM-1 but I do not see...

Re: Adding Wifi to Existing Product

Thanks for the response. Looking at the ESP-Hosted mode it seems that needs SPI to interface to the ESP32(-MINI, in my case). Not sure I'll have that module resource available. Might only have a uart, which could force me into AT command mode. I'm not sure if (or how at this point) packets are recei...

Currently the product is accessed over ethernet for udp control commands, web server, and code updates. We are hoping to use the ESP32 as a ...
