I have been using AI-v0.9.5.0 AT Firmware.bin, and not downloaded any custom code.
what does busy p... stand for ? how to resolve it ? why does ESPlorer does have "Send Data" in tcp server Section ?

He demonstrated how to use ESP in server mode, i have done that. Issue is am not able to use ESP in tcp client mode.

What is the current mode of your ESP?

Possible mode values:

1. Station mode (client)
2. AP mode (host)
3. AP + Station mode (host and client)

Query:

Set:


To use an ESP8266 as a client, it must be set to either 1 (client only) or 3 (client and AP/host).
