as you can AT+CWLAP always responde just scandone and not the list in both modes 1 or 3.
and a few others cmd not responding.

- Sat Jun 10, 2017 6:50 pm #66996 @cardmaker: I have to be honoust that I haven't got a clue of what could be wrong.
Are you using an ESP-01 (by the looks of your first posts and the log it appears to be) or another model?

Maybe it's a good idea to buy a couple of others (and other models, like the ESP-12 or even a actual development board) to rule out issues with your current board.

[UPDATE]
Other things you can try:

• Enter AT+RESTORE: this will restore your ESP to its default settings
• Enter AT+CWLAPOPT=1,127: this will set all options to show in the AT+CWLAP command
• Search the forums of Espressif for similar topics

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

- Mon Jun 12, 2017 3:32 am #67034 Hello, my esp model is this one in this picture:



is the esp8266 001 al-cloud inside

AT+RESTORE this cmd responde and do a reset lyke the AT+RST

thisn one AT+CWLAPOPT=1,127 not repond.

im trying in varius modules because i have many pcs same model.

- Mon Jun 12, 2017 7:32 am #67040 I searched my ESP-module collection and found an older (brand new) ESP-01 (I also have the S-version with optimized PCB layout).
I plugged it into my bread board and it did exactly was it is supposed to do:

Booting @74880 baud directly after reset:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 1396, room 16
tail 4
chksum 0x89
load 0x3ffe8000, len 776, room 4
tail 4
chksum 0xe8
load 0x3ffe8308, len 540, room 4
tail 8
chksum 0xc0
csum 0xc0

2nd boot version : 1.4(b1)
  SPI Speed      : 40MHz
  SPI Mode       : DIO
  SPI Flash Size & Map: 8Mbit(512KB+512KB)
jump to run user1 @ 1000

Then it boots further @115200 baud

Code: Select all▒l`▒n't use rtc mem data

ready

...and I can enter commands:

OK

Note, however, that I've used the original firmware that came with it:

Code: Select allAT+GMR
AT version:0.40.0.0(Aug  8 2015 14:45:58)
SDK version:1.3.0

I haven't updated it to the latest version yet; maybe you should try an older firmware version instead.

[UPDATE]
After having another look at the ESP-matrix, it looks like the ESP-01 can have different size flash memory installed.
Both of my ESP-01's have 8Mbit, while normally it's only 4Mbit in size; perhaps yours are only 4Mbit (though that doesn't explain why you don't have checksum errors at boot).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
