DpaVer DPA protocol version
• 1st byte: bits 0-6 = minor version
• 2nd byte: major version
BCD coding is used, e.g. version 12.34 is coded as 0x1234, i.e. 1st byte 0x34, 2nd byte 0x12
UserPerNr Number of all non-embedded peripherals implemented by Custom DPA Handler. Implemented peripherals are flagged at the UserPer variable-size bitmap array. At the Enumerate Peripherals event, the field is prefilled by 0x00.
EmbeddedPers Bits array (starting from LSb of the 1st byte) specifying which of 32 embedded peripherals are enabled in the TR Configuration (it is a copy of the first 4 bytes of the configuration area). If a peripheral is enabled in the configuration although it is not supported by the device, then calling Get peripheral information or Get information for more peripherals will return PERIPHERAL_TYPE_DUMMY peripheral type for this peripheral thus indicating that the peripheral is not available.
Bit values for Coordinator (bit 0) and Node (bit 1) peripherals are set according to the device support of these peripherals regardless of actual bit values stored at TR Configuration. The bit for OS (bit 2) is always set. The bit for FRC (bit 5 at byte index 4) is always set at [C] device.
HWPID Hardware profile ID, 0x0000 if default. At the Enumerate Peripherals event, the field is prefilled by 0x0000.
HWPIDver Hardware profile version, 1st byte = minor version, 2nd byte = major version. At the Enumerate Peripherals event the field is prefilled by 0x0000.
Flags Various flags:
• bit 0 Device works in STD-RX mode.
• bit 1 Device works in LP-RX mode.
Bits 0 and 1 are mutually exclusive.
• bit 2 STD+LP network is running, otherwise STD network.
The value is undefined in the case of unbonded [N].
• bit 3-7 Reserved
UserPer Bits array (starting from LSb of the 1st byte) specifying which of the non-embedded peripherals are implemented. 1st bit corresponds to the peripheral 0x20 = PNUM_USER. The corresponding bits must be set at the Enumerate Peripherals event. The length of this array can be from 0 to 12 bytes depending on the last implemented user peripheral number. the number of bits set in the bitmap must equal the UserPerNr.
