The resulting functionality of a TR transceiver is determined by the following application files uploaded inside:
● DPA plug-in (.IQRF):
Implements the principal functionality of TR (Coordinator / Node, RF mode STD / LP, Interface SPI / UART / none, …). Refer to IQRF DPA Framework Technical guide, chapter DPA Plug-in filename.
Contains the configuration parameters such as RF channel, TX power, Access Password, etc. Refer to IQRF OS User’s guide, chapter TR Configuration, IQRF DPA Framework Technical guide, chapter TR Configuration, and IQRF IDE Help, chapter TR configuration. TR configuration can (but need not) be the same in all TRs (depending on the application). It can be changed later on even in the existing network.
Recommendations:
• Start with the default configuration predefined in IQRF IDE.
• Set a non-default Access Password, unique for each network. Access Password is used for bonding, authorization in DPA Service Mode (DSM) and encryption and decryption of backup data during the Backup / Restore process intended for an easy replacement of a TR in the network (when needed).
• Accomplish a frequency planning, i.e. select a free operating channel (not jammed). The CATS - RF Scanner would help.
• You need to configure an operating channel at the Coordinator only. This channel will automatically be inherited by all Nodes during bonding (and written to their TR configurations).
