• Those are kind of special, you can find them in 16bit uuid pdf here https://www.bluetooth.com/specifications­/assigned-numbers/

    GATT Service
    0x1800 Generic Access
    0x1801 Generic Attribute

    GATT Characteristic and Object Type
    0x2A00 Device Name
    0x2A01 Appearance
    0x2A02 Peripheral Privacy Flag
    0x2A03 Reconnection Address
    0x2A04 Peripheral Preferred Connection Parameters
    0x2A05 Service Changed

    They need to be implemented in specific way for BLE/GATT to work properly so you control them by calling specific softdevice APIs or passing specific data/flags. You can't implement them yourself in javascript. At least the 0x2A04 Peripheral Preferred Connection Parameters and 0x2A05 Service Changed are pretty important to work as expected or stuff will break.

    So yes you can make espruino to look the same but by modification of C source in https://github.com/espruino/Espruino/blo­b/master/targets/nrf5x/bluetooth.c

  • Thank you @fanoush, it's good to know that it can be done. :)

    Espruino is only missing 0x2A02 0x2A03 and 0x2A05, their value is not used, just their existence.
