    Powered Up - A tear down...

    Which is the best way to check if a motor is stalled? I noted that if block a tacho motor i get a message "port feedback" (0x82) with value 0x2C, and the the current on the relative port is shutdown. The payload of port feedback is a "bit field" and 0x2C in binary is 101100 From LWP documentation: Bit 1: 0x01 Buffer Empty + Command In Progress Bit 2: 0x02 Buffer Empty + Command Completed Bit 3: 0x04 Current Command(s) Discarded Bit 4: 0x08 Idle Bit 5: 0x10 Busy/Full But bit 6??? Bit 6: 0x20 ??? Someone have more information?

    Che command for request the FW Version is: 0x04 0x00 0x01 0x03 0x05 0x00 0x01 0x03 0x05 Read here to know how to decode response: https://lego.github.io/lego-ble-wireless-protocol-docs/#ver-no

    I'm sorry... i wrote a wrong thing. This is a "Device attach" message. 01 is "Attach event" 06 is "Device type" (determinate by resistor value). However, if you send a Port Information Request to the Hub, the same message is returned as reply. In this case, 01 is "Information mode and 06 is capability ;)

    I try to "play" with the smart hub. I cut a LED cable and i connect the pin 5 & 6 (and gnd) to USB to Serial TTL adapter. After, i connect to smart hub via Bluetooth and send a command to subscribe notification. When plug the cable to smartphone i obtain this message: 0f 00 04 00 01 06 00 00 00 00 00 00 00 00 00 It's a Port Information Message (04), for port A (00), Information mode (01) and capability (06). 06 = 00000110 = Logical Combinable, Input (seen from Hub). I try to send bytes from serial monitor but, obviously, not knowing the "wired" protocol, I was not able to receive any notification on the bluetooth side. I try also to send one byte (and relative checksum) with command 0x81, 0x50 (WriteDirect) but without success. :(

    I have opened the Boost Sensor. This use the STM8S1054K chip with the LQFP32 pinout (8 pin for side) Note: the numbers I write on the cable conform to the image of this post, but on the PCB are inverted.

    I'm sorry for the duplicate :( No. But i hope in a someone that find the way to do it. Or better, i hope also in a full documentation from TLG. Nope...

    There is a strange thing .... Under the battery pack there is a soft button (reset?) which can only be pressed by removing the battery pack ...

    Control+ internals. The processor is an 80Mhz (instead 48Mhz of the PU Hub) and the motors driver is a LB1836 There is a n.4 chip signed ad H25 02 27 x842 (each for single output port) but i don't sure what features they implement. (maybe they are dropdown linear regulator?) Macros:

    The steps to change the name of the hub (saved in flash memory) from the App https://itlug.org/forum/topic/7615-lego-poweredup-aka-power-functions-20/page/3/?tab=comments#comment-75176 P.S.

    Another interesting thing about "distance sensor": Back of the sensor (break-out): • Can be detached from the front of the sensor by removing two screws • Provides access to an 8-pin female header that allows direct and easy access to the LPF2 system for adding third-party sensors and boards
