- Sat Feb 06, 2016 7:19 am #40557 Just installed it for the first time (on my own PCB) and am impressed how good the serial link works. I have a xmodem bootloader in the micocontroller. Connecting to port 23 and uploading with teraterm - which supports xmodem over TCP/IP ports - works flawlessly.

I noticed a minor problem in the uC console with 2.2beta1: If the MCU sends '<' or '>' characters, e.g. a menu string such as "<q> = quit", the console doesn't show the <..> part. Probably related to < and > being HTML characters.

On the wifi configuration page, the signal strength of all detected networks (in my case varying from -69db to -90db) is represented by the same symbol, four of five bars. Is that working as intended?

The site mentions a fail-safe, which is "that after a reset or a configuration change, if the esp-link cannot connect to your network it will revert back to AP+STA mode after 15 seconds". Wouldn't it be better if it always was in AP mode for a minute after a reboot? That would resolve the situation if a user accidentally connects to an open wifi network not under his control. As an alternative, it could be useful to force esp-link into AP mode by pulling GPIO0 low for 5s (GPIO0 should already be under control of a jumper).

- Fri Feb 26, 2016 5:59 am #41927 Firstly, thank for a great job.

I use Release 2.2.beta1, Arduino Uno and el-client library.

Run "examples/rest/rest.ino" and got the picture http://i63.tinypic.com/2uomkup.jpg
And it constantly all the time one and the same garbage.

As you can see I am getting some garbage instead of "2016-02-25T13:12:13+00:00" for example.

How do get the text result?

- Sun Feb 28, 2016 6:55 am #42040 Congratulations and many thanks for this great project! It is truly awesome.

I have a problem with OTA though. I have an ESP-07 with a 1MB chip (confirmed by checking the IC) but esp-link thinks the flash size is 512K only, hence OTA won't work. I have updated the Makefile with FLASH_SIZE ?= 1MB and did a clean compile. But this doesn't seem to make a difference. Am I doing something wrong?

Code: Select allFlash chip ID     0xE0 0x4014
Flash size        512KB:256/256

- Sun Apr 24, 2016 5:04 am #46065 Fantastic product - thanks. So easy to install and configure.
However, I can't get it (stable, beta) to work for my main usecase, which is Firmata protocol over wifi.
Arduino (e.g. uno) running Firmata, connected to esp-link, wifi to my Node-red server running a Johnny-five node.
Everything looks right - testing with a simple hello-world sketch etc on the arduino works perfectly end2end.
But Node-red Johnny five node can't see the traffic - it's setup with a node taking remote IP and TCP port (23), but it doesn't see the traffic. I had marginally more luck mounting a virtual tty under /dev with Socat - at least then it could connect. But still not able to see the data.
Has anyone got Firmata/Johnny-five working over esp-link? I'd love to resolve this ....
