[BK7231N/CBLC5] Difference Between WiFi and Bluetooth Versions of GU10 Tuya RGBCW Bulb [BP5758D]?
Main board designation: SY-GU10-5L-WIFI-BL
LED board designation: XB-05257
I was really surprised to receive this bulb with a WiFi module, instead of a bluetooth one (and i ordered the bluetooth version specifically).
The only difference between them, as far as i have seen, is that WiFi version use short bare wires, whereas bluetooth one is using long, insulated ones.
(Which is the reason the board is damaged, it was a lot harder to remove it from the housing)
Tuya config:
I wouldn't recommend using it on stock firmware.
CW current from config is 33mA, which is really high.
Even on GX53 i only got 24mA in tuya config, and on the modded bluetooth ones i set to 8mA.

Device configuration, as extracted from Tuya:
- BP5758D_DAT on P26
- BP5758D_CLK on P24
- LED remap is 2 1 0 4 3
Device seems to be using CBLC5 module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424
I wouldn't recommend using it on stock firmware.
CW current from config is 33mA, which is really high.
Even on GX53 i only got 24mA in tuya config, and on the modded bluetooth ones i set to 8mA.

Interesting, was it marked as Bluetooth-only or Bluetooth AND WiFi? CBLC5 has both BT and WiFi. Theoretically they could use CBLC5 as Bluetooth only device as well, but I don't think it would be worth... [Read more]
Can't properly verify this template - this was the only available bulb for esp32-c2 testing, so i replaced the main module with wroom-07 one. Wifi version was probably sent by mistake - those that i have... [Read more]
Another bluetooth version arrived, this time it was bluetooth only with long wires, as expected. Newer board revision, marked as V2, SDA/SCL pins are also named. Btw, why was this topic renamed and... [Read more]
Sorry, you are right, I have moved it to Teardowns now. Well, so that's how BT versions looks like, SY801-E, I see. This IC in SOIC case is not marked? It looks much more cheap than WiFi version. Interestingly... [Read more]
