Other Parts Discussed in Thread: WI-SUN, , SYSCONFIG
Hi,
We are currently developing a Wi-SUN solution based on the CC1312R7 with a Front End Module.
The hardware team designed the front end to be external bias, single-ended mode RFN for RX operation and RFP for TX operation.
Initially using SmartRF Studio 7, we configured board using "Custom Target Configuration" for RFN RX and RFP TX respectively.
During Modulated TX, we've observed roughly the expected TX power on the spectrum analyzer ~30dBm.
Next, using CCS 12 and SDK simplelink_cc13xx_cc26xx_sdk_6_20_00_29, we started an example project rfDiagnostic and set custom board configuration with sysConfig. Please see attached zip for the rfDiagnostic firmware source code.cc1312r7-rfdiagnostics-firmware.zip
Following swra640g.pdf, we've set the front end to be Single-ended RFN and added the ADI_HALFREG_OVERRIDE(0, 16, 0x7, 1) in sysConfig's Application Override Macro. When we run the rfDiagnostic in Modulated TX test mode, we've only observed ~15dBm TX power. When we tried to remove the ADI_HALFREG_OVERRIDE(0, 16, 0x7, 1), we've observed no change in the TX power.
Please advise on how to properly setup the firmware for RFN RX and RFP TX.
Regards,
Alex
