Part Number:CC1312R
I'm working with a customer on the process for FCC certification of their custom design. It appears that their test house is familiar with the SmartRF Studio tool, but I have some questions about the procedure.
First off, it is clear that SmartRF Studio can be used through JTAG in order to setup the device for both continuous RX and TX modes. In this setup, the customer application does not run. It would seem however that it is likely not okay to have a PC with a USB connection to a JTAG emulator actively connected to the board, in the test chamber, during the test. Does anyone do that and is it considered valid?
...so, how does one start the test mode (using SmartRF Studio over JTAG) and then disconnect from the target board in order to remove the PC and emulator from the chamber while the test mode on the device continues? Is it possible?
Alternatively, I see that "Code Export" might be an usable option, but I'm not sure. My thought is that we would setup the mode we want to run (Continuous TX, Channel, Tx Power, etc...) and then choose "Code Export". Then we would drop the smartrf_settings.h and smartrf_settings.c into the application project. If the application were then run with these settings, would the result be that the application would now be in the same mode that we setup from SmartRF Studio? Would there be additional code changes required in the application? Are there some "startup" calls that need to be made?
One of the concerns I see right away is that when I double click on the CC1352R device in SmartRF studio (I'm using a CC1352R launchpad as a stand in for a CC1312), it will only open up in 2.4 GHz mode for IEEE 802.15.4 mode? Is there a way to open it up in sub-1 GHz mode? I'm using SmartRF Studio 7 version 2.12.1.
Second, It seems, according to the customer, that the TI 15.4-stack examples have some kind of configuration option for "certification mode", and that this mode does some kind of much faster communication and reception interval, though not 100% TX duty cycle. Is this supposed to be used in some way in the FCC certification process? Is it an alternative to SmartRF Studio in some way?
Thanks,
