Teardown of EUROLAMP Smart Wifi RGBW E27 and GU10 Bulbs with BK7321N and BP1658 Modules

soulslayer 

Here is a really quick teardown of two EUROLAMP RGBW bulbs, an E27 and a GU10.
From what I've gathered, this brand is exclusively in the Greek market, so you probably won't ever see it.

E27:

This one was my first lab rat, and I had a small accident as you will notice in a bit 😅
It uses the BK7321N CB2L module and the BP1658 driver.

GU10:
https://www.eurolamp.gr/en/product/Smart_Worl...ART_WiFi_LED_GU10_6W_RGBW_220-240V-147-77903/

When opening this one, be careful as the WiFi antenna is folded just under the cap; if you accidentally change its shape, it will not work.
Also, the LED PCB/heatsink is glued to the main board, so don't try to pry it (because you'll tear the pads and need to repair it lol).
It uses the BK7321N CBLC5 module and the BP1658 driver.

I also dumped the firmware for the GU10, so it has a cloudcutter profile 🚀

Hello, can you attach here either 2MB dumps for each device, or maybe a OBK Web App template? [Read more]

Attached the dump and profile link. Unfortunately, I only dumped the GU10 as the E27 was fried. [Read more]

Ok, so GU10 config is: { "rstnum":"3", "rstcor":"c", "Jsonver":"1.1.9", "brightmin":"10", "gmwb":"75", "title20":"0", "deftemp":"0", "gmwg":"70", "wfcfg":"spcl_auto", "colormin":"10", "pmemory":"1", "gmkb":"60", "iicb":"2", "cjccur":"2", "cmod":"rgbcw", "mixway":"0", "iicscl":"26", "wt":"10", "cwtype":"0", "prodagain":"0", "rstbr":"50", "remdmode":"0", "colormax":"100", "cagt":"10", "iicw":"3", "notdisturb":"0", "module":"CBLC5", "cjwcur":"3", "colorpfun":"0", "iicsda":"24", "cwmaxp":"100", "iicc":"4", "dmod":"5", "gmwr":"100", "rgbt":"10", "gmkg":"60", "onoffmode":"0", "brightmax":"100", "iicg":"0", "wfct":"3", "rsttemp":"0", "category":"0505", "gmkr":"80", "iicr":"1", "defcolor":"c", "defbright":"100", "crc":"45", "}3fkAwf_start_md3bLdAgw_di{abi":"0", "id":"null", "swv":"1.2.16", "bv":"40.00", "pv":"2.2", "lpv":"3.3", "pk":"key8u54q9dtru5jw", "firmk":"key8u54q9dtru5jw", "cadv":"1.0.3", "cdv":"1.0.0", "dev_swv":"1.2.16", "s_id":"null", "dtp":"0", "sync":"0", "attr_num":"0", "mst_tp_0":"0", "mst_ver_0":"null", "mst_tp_1":"0", "mst_ver_1":"null", "mst_tp_2":"0", "mst_ver_2":"null", "mst_tp_3":"0", "mst_ver_3":"null...

Also, for some reason cool white and warm white were swapped with that profile. I had to change the config like this for it to be correct: https://obrazki.elektroda.pl/7882329000_1702029527_thumb... [Read more]
