MYDSN - Local Device Serial Number
Non-Volatile Address = 0x34-0x37
These registers contain the factory-programmed read-only Device Serial
Number. This address is unique for each module and is included in all
packet types as a unique origination address.
Figure 57 shows the Device Serial Number registers.

CSRSSI - Carrier Sense Minimum RSSI
Non-Volatile Address = 0x3F
This value is the minimum RSSI that causes the module to wait for a
clear channel when CSMA is enabled. Figure 59 shows examples of the
commands.

The value is a negative number in two's complement from -128 (0x80) to
-1 (0xff). The default value is -92dBm, which is the maximum limit for ETSI
compliance.
!
Warning: The CRSSI value can have a significant impact on the
performance of the module. Setting it too low could prevent the module
from ever transmitting. Setting it too high can result in transmission
collisions. Care must be taken if this value is adjusted.
Note: Changing this setting from its default value of 0x02 invalidates the
HUM-868-PRO module Declaration of Conformity (DoC).
