LYT8266 Flashing

[Christian Glomb]

I own an LYT8266 and am neither able to connect to it nor to flash it:

When I power on the bulb taken out of the box, I see a wifi hotspot called "LYT8266" to which I can connect and ping 192.168.4.1. However there is no web server running such that I can't configure anything via: http://192.168.4.1

The next approach was to load one of the Arduino example sketches onto the bulb using the following cable:

http://www.ebay.com/itm/USB-To-RS232-TTL-UART-PL2303HX-Auto-Converter-USB-to-COM-Cable-Adapter-Module-/181847253057?hash=item2a56f0e041:g:BFAAAOSw0e9Uw5QL

I connected:

ESP03_URXD (bulb) -> TX (USB cable)

ESP03_UTXD (bulb)  -> RX (USB cable)

GPIO0 + GND (bulb)  -> GND (USB cable)

while the bulb is turned off. Arduino IDE can't connect and therefore the sketch can't be flashed.

Shall I now turn on the bulb and flash it or is there an additional pin to connect the 3,3V PIN from the USB cable (resoldered as described here: http://hanneslehmann.github.io/2014/12/ESP8266Module/)

Any hints desperately welcome!

[Domenico Carvetta]

I never used the ESP03, but I think should be the same as described as ESP01.

I guess the connections should be ok (vcc, ch_pd both to 3.3V, gpio0 to gnd, cross rx and tx pin as you did, and finally gnd to gnd).

Then, toggle the power up and flash it; so making should works fine!

[Christian Glomb]

No way! Even when soldering the wires directly to the ESP I get:

warning: espcomm_sync failed

error: espcomm_open failed

error: espcomm_upload_mem failed

[Christian Glomb]

Think I'll try with another programmer. Any good ideas which one to use?

[Domenico Carvetta]

Try step by step; it's no easy to drive you to the solution due to few data you provided us.

Anyway, try this:

http://eu.banggood.com/Wholesale-Warehouse-FT232RL-FTDI-USB-To-TTL-Serial-Converter-Adapter-Module-For-Arduino-wp-Eu-917226.html

[Domenico Carvetta]

and let us know!

[Christian Glomb]

After additionally soldering CH_PD to VCC I could flash e02_LYT8266_WiFi_Erase!

Now fiddling around with the version chaos to compile and flash  e02_LYT8266_WiFi_Bulb...

error: cannot convert 'String' to 'const char*'

[Domenico Carvetta]

So that now are you able to flash the esp ? right?

If so, pls send me the sketch ..I could compile it from my side just to trial run.

[Christian Glomb]

Finally flashed  e02_LYT8266_WiFi_Bulb via NodeMCU flasher. Hope that works such that I can use the OTA functionality now.

As a wish I would propose that you deliver the bulbs with some OTA firmware already installed such that users have a better start.

Thanks Domenico and Dario (via Email)!

[Domenico Carvetta]

Good news!

[Domenico Carvetta]

any other help ?

[Christian Glomb]

Just tried - it works such I can connect the bulb to my WiFi!

Since I don't have an Android device I'm looking for a way how to control the bulb via openHAB. The idea is to have two sliders, one for brightness (zero brightness = off) and one for changing the color. Is there already a solution to realize this?

Thanks again!

[Christian Glomb]

Is there any way to store WiFi info on the bulb? Currently the settings are lost when the bulb is switched off such that I have to reconnect to my WiFi again.

[Domenico Carvetta]

For both previous posts, it depends on the sketch you are using; pls post it, and then we will see!

Thanks !!

[Christian Glomb]

It's the "e02_LYT8266_WiFi_Bulb.ino" from the souliss examples.

[Domenico Carvetta]

Ah ok.

It uses the OTA function; for now I don't use this function yet.

But you can easily modify the overall sketch to use the istructions as follows.

In order to start it's more easy and you can learn much more.

In case, you can ask....

// **** Define the WiFi name and password ****

#define WIFICONF_INSKETCH

#define WiFi_SSID             "xxxxxxxxxxxxxxxxx"

#define WiFi_Password         "zzzzzzzzzzzzzz"    

Try it !!

[Di Maio, Dario]

The module always save the wifi password, if is not working you are probably using a wrong Flash setting on the IDE.

You can any how use a password directly in the sketch as suggested by Domenico. There are examples in WiFi folder that shows how to.

[Christian Glomb]

You are right. The connectivity was lost due to weak WiFi.
Any hints for the openHAB binding? I already have a slider in the UI but need to bind it to the appropriate command.

[Flavio P.]

Hello Christian,

you can see souliss typicals, to select the needed logic profile.

With your slider, i can assume you want to control a pwm output, in this case i can suggest you to use T16 or T19 typicals.

For OH binding, generally you must:

   -add the binding(.jar file) to your addons folder

   -configure in your openhab.cfg file(make sure to insert the correct souliss gateway IP)

   -configure your logic profile on your .items file like {souliss=<Typical>:<nodeID>:<slot>:[<bit>]}

   -configure your items on your sitemap file

Example for T16:

Color  RGB_Led_Strip_1 "RGB Led Strip 1" <slider>           {souliss="T16:0:2", autoupdate=false}

This line configure a T16 typical in your node 0 on slot 2.

Hope this can help you ;)

Flavio

So even I. have a light bulb (T15) I should use T16 (light strip)? Is the LYT8266 being controlled as a light strip?

[Flavio P.]

No no, if you have a T15 on board side it's ok and OH should work....isn't?

The bulb doesn't react and no errors can be seen in /var/log/openhab/openhab.log. Any ideas how to easily check the connection between openHAB and the bulb?

One step back, with soulissapp work fine?

Can't test that since I don't have an Android system.

[Flavio P.]

Sorry Christian, I've checked only now( I suppose you made this control before start with OH binding), but T15 are not available in the binding. 

You can change with a T16 I think, but I've never seen a LYT, generally rgb led bulb, but I don't now how to integrate code with LYT bulb.

You can use an emulator, like bluestacks.

http://www.bluestacks.com/

With soulissapp you can make some test without write code, you can use one of the example on board side and have a working system in a few minute.

Once your system work, we can step to OH.

Thanks, I'll try that. More complicated than I thought.

LYT are devices that has their own Ligics as in the relevant examples, use those and it will work in openHAB as T16.

Used the example sketch that the Arduino Souliss Lib provides and tried with T16 but no reaction.

[Christian Glomb]

At least openHAB receives something: 2016-07-16 23:43:05.838 [INFO ] [.o.b.s.internal.SoulissBinding] - receiveCommand - LYT_BULB_C = 62 - Typical: 0x16

Might there be some index mis-configured?

Install Blue Stack on your PC to emulate Android and ensure that your light is working fine.

Partly successful with T16:0:0: When I configure a Switch for the Bulb then I can turn it on via openHAB. However, there is no feedback from the bulb such that openHAB doesn't detect that it is turned on. What might be the reason for that? Might that be the cause that Dimmer and Color don't work?

[Christian Glomb]

Any ideas or maybe a working example (openhab.cfg, .items, .sitemap)?

[Christian Glomb]

Strange:

- Leaving out autoupdate makes the slider work, but only from the iOS App (Slider sends values between 0 and 100).

- Slider behaves differently on the browers UI (sends Increase / Decrease instead of values).

[Christian Glomb]

Seems to be this issue: https://github.com/openhab/openhab/issues/4215

[Christian Glomb]

OTA sketch upload also doesn't work: [ERROR]: No response from device

[Domenico Carvetta]

The OTA function should work using as follows:

- IDE 1.6.8

- Souliss 720_rc branch

- core 2.1.0

The ESP must be the esp12f version; all the others have some unknown issues and maybe will not work!!

I hope now it's more clear.

[Christian Glomb]

But LYT8266 has a ESP-03, hasn't it? And here Dario says that OTA works with LYT8266.

[Di Maio, Dario]

I've OTA with LYT but with IDE 1.6.5 and 7.1.1 and old cores, not yet tested OTA with 7.2 and IDE 1.6.8.

Anyhow OTA is a core function and is not directly related to Souliss, issue may be arise even if we doesn't change our code.
