(version of my esp01: Vendor:www.ai-thinker.com Version:0.9.2.4 AT+GMR0018000902-AI03)

1. esp8266 can be set as invisible/hide ssid? if so, what is the AT command?
2. esp8266 can be set to work only in mode 802.11n? in mode N have lot of RF power (Transmit 802.11b, CCK 1Mbps, POUT=+19.5dBm)
3. the AT+RFPOWER , AT+RFVDD and AT+RESTORE command i get error response. i did AT+RFPOWER=50, get error.... how i set ESP to work in full Tx power mode?
4. is the last firmware? Vendor:www.ai-thinker.com Version:0.9.2.4 AT+GMR 0018000902-AI03

soooo, after 2 days i finally manage to upload (i think) maybe is a problem with bins or i did something wrong the problem is when i try to set a AT command or restart the module. after i reset the module i cant send any AT command, when i press reset buton on module i get that chars no mather what i do, power down, back, reset etc, i use a cp2102 module and 1117 3.3/1A LDO to power the ESP. so i do up the bins again and get the AT, AT+GMR work, if i reset.... random chars and esp not respond. ohh and i put a old version boot_v1.1 seems to work, but is old one
first pic ok, until..
second pic the problem

Hi,
If your flash size is 4Mbit,please upload using NON-BOOT MODE bin(refered to esp_iot_sdk_v1.4.0\bin\at\readme.txt):
eagle.flash.bin : 0x00000
eagle.irom0text.bin: 0x40000
blank.bin : 0x3e000 & 0x7e000
esp_init_data_default.bin (optional): 0x7c000

yes is 4 mega flash (25Q40BV). non boot mode is over wifi? because i dont have wifi router, all i can is usb/cp2102 to ESP http://www.banggood.com/ESP8266-Remote-Serial-Port-WIFI-Transceiver-Wireless-Module-p-947259.html, and i need the correct address for each bin.

You can write bin into flash using flash_download_tool.exe via uart.

eagle.flash.bin : 0x00000
eagle.irom0text.bin: 0x40000
blank.bin : 0x3e000 & 0x7e000
esp_init_data_default.bin (optional): 0x7c000
