This is not clear? Does this mean that output back to, say an Arduino is now buffered? and if so.. how does a user of the BIN file make use of this - which pin is used for handshaking? Is it one of the two available on the ESP-01 (ie GPIO0 or GPIO2) ?? How is it used?

The readme file in APP is out of date and refers to SDK v0.9.2 - it shows only 3 binary files....

Pete.

1. How to compile and download?
viewtopic.php?f=7&t=25
without upgrade :
esp_init_data_default.bin-->0x7c000
blank.bin ==> 0x7e000
devkey --> 0x3e000(do not need for at)
eagle.app.v6.irom0text.bin-->0x40000
eagle.app.v6.flash.bin --> 0x0

with upgrade function:
esp_init_data_default.bin-->0x7c000
blank.bin ==> 0x7e000
devkey --> 0x3e000(do not need for at)
user1.bin-->0x01000
bootv1.1.bin --> 0x0

2. Does this mean that output back to, say an Arduino is now buffered?
This is a data buffer for data received from wifi tcp interface.
Uart speed is about 11kbps , and tcp speed is more faster than that, e.g.8Mbps...
So there is a data buffer for data from wifi to uart tx.

3.Handshake pin
viewtopic.php?f=7&t=28
in this topic ,you can find the pin function definition.
U0TXD=>pin:U0TXD
U0RXD=>pin:U0RXD
U0CTS=>pin:MTCK
U0RTS=>pin:MTDO

Or , viewtopic.php?f=7&t=22
in this topic you can find out a way to swap these pins.

4. I guess you dont want to change anything, so just use the attached bins.

[quote="scargill"]"Also why is the AT command set not compiled SDK 0.9.4? "

Hi：
There are some small changes in library of SDK v0.9.4 , so that AT0.20 has to be changed at header file. Below is a modified method:
https://github.com/espressif/esp8266_at

In future, when we release new version of SDK, and AT must be released together. means names “AT for SDK v0.x.x”.

Enjoy!!

no the pins for hardware handshake are MTCK and MTDO (pin 12 and 13 if i right remember), not available on all modules.

i think that a new AT command need to be added to enable/disable the handshake.
the handshake is really necessary only for a full web server host.

For new people coming into this - and those of us with short memories, in the BIN file could you please add a text file with locations to save the various BIN files. There appear to be 5 bin files in new release.

Also why is the AT command set not compiled SDK 0.9.4?

"1.ADD UART TX BUFFER TO RECEIVE DATA FROM TCP PORT

2.ADD A UART TX FLOW CONTROL VIA MTCK( CTS )
//SET_PERI_REG_MASK( UART_CONF0(uart_no),UART_TX_FLOW_EN); //add this sentense to add a tx flow control via MTCK( CTS )"

This is not clear? Does this mean that output back to, say an Arduino is now buffered? and if so.. how does a user of the BIN file make use of this - which pin is used for handshaking? Is it one of the two available on the ESP-01 (ie GPIO0 or GPIO2) ?? How is it used?

Hi：

It is also to pay attention to “AT+CWSAP=...”, if you SDK version is v0.9.3 and AT v0.20.

There is something wrong when set softAP ssid , Because SDK v0.9.3's wifi_softap_set_config() has been changed.

if you get in trouble, look to me:
【Link Address】↓
https://github.com/espressif/esp8266_at ... 087fd3df7b

---------------------------------------------------
v0.9.3及以后版本的struct softap_config结构体有变动，增加了ssid_len一项，执行函数 softap_set_config()时，需要设置一下ssid_len。

Enjoy！！
