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 ?

#66166 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:
Code: Select allAT+CWMODE?

Set:
Code: Select allAT+CWMODE=<required mode>


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