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.

CUSTID - Customer ID

Non-Volatile Address = 0x39-0x3A

These registers are not used by the HumPRCTM application and do

not have any effect on its operation. Figure 58 shows the Customer ID

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).
