LARGE UDP Reception delays!!!

Hi We have designed an ESP32C3 into a motion control device but have a BIG problem with delays when receiving UDP frames. There is a UDP frame received every 50ms consisting of 1024 bytes of data which then controls a motion output. Jitter in the UDP reception of 10s of ms is acceptable but sometime...

Re: How to resolve ESP32 AP to a name?

Hi

Another point.

I don't see why the TCP port is required as a parameter since I also see no reference to the TCP port during the mDNS resolution.

Regards

Re: How to resolve ESP32 AP to a name?

Hi After experimenting with different service types I find no change in behavior. Also I have monitored the mDNS process and don't see that it is used in any of the queries or replies. The problem at the moment is the time it takes to resolve - the browser spins for about 15s before it connects. The...

Re: How to resolve ESP32 AP to a name?

Hi Thank you. It sounds that when using port 80 "http" would be the better service type entry to use. Presently, although the resolution is working, it is taking about 15s before it operates. I retested with "http" set but it didn't seem to make any difference and it still takes a long time before i...

Re: How to resolve ESP32 AP to a name?

Hi

Many thanks!!!

I tried
AT+MDNS=1,"espressif","_iot",80
and that did allow connecting on the ULR espressif.local

I haven't yet understood what the "_iot" means but this is a good start since it is much better than needing to know the IP address!

Regards

If I use the standard ESP32-AT is this possible?

How to resolve ESP32 AP to a name?

Hi All I have an ESP32-S2-MINI and have a web server on port 80. To connect to it I use (from a browser) http://192.168.4.1 It is possible to use some technique to be able to browse to it by name instead of its IP address? Eg. http://MyESP32 (I have used NetBios to do something similar in the past o...

Losing TCP reception payload

Hi All I am using the ESP32S2-MINI in AT mode (125kBaud) via UART in order to upload new code to the main processor over a HTTP connection. The new FW is about 800k in size but I find it randomly failing after typically about 128k of the upload - this various and so this is only typical but it is ve...

Re: Using two servers (HTTP and TELNET ports)

Hi Thank you for the information. For the UDP case I need to have a TCP server and receive UDP data at the same time (in fact I don't actually need to "transmit" UDP data). This probably means that it can't be done either with ESP-AT without customising it (?) At the moment I am also trying to build...
