BLE_SEC_CONFIG
The BLE_SEC_CONFIG register is used to configure security settings that are specific to BLE
telegram transmission.
The BLE_SECURITY_MODE field is intended for future implementation selecting the security
mode used by PTM 535BZ when transmitting BLE telegrams. Currently, the supported secu-
rity mode is using a 32 bit sequence counter to generate a 32 bit CMAC (signature) as de-
scribed in
Chapter 3.4.2
The BLE_KEY_SELECTION field is used to select the security key used for the authentication
of PTM 535BZ data telegrams as described in
Chapter 3.4.2
and for the generation of Re-
solvable Private Addresses as described in
Chapter 3.3.5.2
. By default, SECURITY_KEY1 is
used; SECURITY_KEY2 can be selected by setting the BLE_KEY_SELECTION field to to
0b1.
Note that SECURITY_KEY2 cannot be read via the NFC interface.
The BLE_LRN_BUTTON field is used to enable and disable transmission of a BLE commis-
sioning telegram if the LRN button is pressed and SECURITY_KEY1 is selected. By default, a
BLE commissioning telegram will be transmitted if the LRN button is pressed and the ECO
200 harvester is actuated. Transmission of a commissioning telegram can be disabled by
setting the BLE_LRN_BUTTON field to
0b1.
