as you can see AT+CWLAP only respond scandone and not the list of avalable network.
and some others cmds never respond.

Please try the new ones from:
https://github.com/espressif/ESP8266_NO ... ter/bin/at

Note that minimum 8 Mbit system flash is needed for the latest AT firmware. If you are using less, let me know, I will send you 4 Mbit AT firmware files.

AI-v0.9.5.0 AT firmware.bin
ai-thinker-0.9.5.2.bin
ai-thinker-v.1.1.1.bin
ESP_8266_BIN0.92.bin
and others but same result.

i know must use \r\n at final

this cmds works: AT+RST, AT+CWMODE=3, AT+CWLAP(just responde "scandone" and not the list), AT+CWJAP="xxx","xxx",AT+CIPSTART="TCP","XXXXXX",XX

but this cmds are not working: AT, AT+GMR, AT+CIPSEND=X,AT+CWMODE=?

they responde to these cmds like AT+CWMODE=3, AT+CWJAP,"xxxx but not respond by exemple just AT, or AT+GMR what can be this issue?

also at comand scan wifi AT+CWLAP they juste replay "scandone" and not the names of the networks, anyone can help?

many thanks
