I've drawn a new release (including pre-compiled firmware, as usual). Now using SDK 1.3.0.

https://github.com/eriksl/esp8266-unive ... ses/tag/11

Changes:

- tcp port the uart bridge listens at is now configurable (see btp command)
- add wlan / access point scanning (see wlan-scan and wlan-list commands)
- optimisation (speed and memory usage, both ram and flash)
- some small bug fixes

Thank you very much for your awesome work! Will test it this week! You will surely get a reply!

It does not connect to my WiFi Access point, I tried two different AP´s already. UART Tells me:

You now can enter wlan ssid and passwd within 10 seconds.
Use exactly one space between them and a linefeed at the end.
Configure wlan, set ssid="Studienarbeit", passwd="123456789
"
f 0, scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 3
pm open phy_2,type:0 0 0
cnt
state: 5 -> 2 (1c0)
rm 0
pm close 7 0 0/3995740
reconnect
state: 2 -> 0 (0)
f 0, scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 3

this repeats endless...

- Mon Sep 14, 2015 9:03 am #29025 Only the last part or including the bootstrap message?

If it's all of it, the esp is resetting, that's propably a hardware issue (connection, power supply, etc). If it's only the last part repeating, that simply says that it can't connect and that's something you already figured

When on firmware update the config has a changed, it's not used and needs to be set again. There are three posibilities.

- new firmware, no change in the config, config remains active
- new firmware, "minor" change in the config, gpio's need to configured (if used)
- new firmware, "major" change in the config, all of the config is reset to it's defaults

I think you're jumping from a firmware version that implies a "major" config change and the config is reset.

This is what you do: follow the instructions from the messages on the UART. So within 10 seconds after bootup, type the name of the SSID, as space, the password and then LINEFEED (= 0x0a, \n, no carriage return!). This sets the WLAN parameters. After that, you should be able to login and set the other config parameters.

Unfortunately I can't use the WLAN parameters set by other firmwares in the SDK NVR area. It simply stopped worked on transition from SDK 1.1.0 to 1.2.0, I don't know why.

- Mon Sep 14, 2015 9:05 am #29026 Sorry I didn't read too well. You did follow the instructions, but incorrectly.

Configure wlan, set ssid="Studienarbeit", passwd="123456789
"

This is wrong. Where did you find this syntax?

It should be like this:

Studienarbeit 123456789^J

(where ^J is typed as control+J).
