First question here so please be gentle

I have 2 ESP-07 1 I have left with the default AI-Tinker FW on the other I have programmed with a transparent bridge project.

Now when I connect to the AI-tinker one I get consistent fast pings of <1ms from my PC. But when I connect to the one with the custom fw based on an SDK 1.1.1 I get slow inconsistent pings

Pinging 192.168.4.1 with 32 bytes of data:

Does anybody have any ideas why that is? I know the AI-Tinker is running custom FW but I thought a ping would be a fast response.

Cheers

The custom firmware must be keeping the CPU busy, causing a delay in the ping response. Since AT command firmware is just waiting for commands, it is doing less work and the CPU is available more quickly to respond to the ping.
