Tool/software: TI-RTOS
Hello all,
I am currently working on a project with the cc1310f128rhb chip. The project includes a simple wire antenna 1/4 lambda with ground plane. Due to the limited measurement equipment I have got to optimize the adaptation of the antenna circuit to the cc1310 I am using a cc1310launchpad as measurement device.
As TI has got the smart rf tool to configure devices to simplified transmitters and receivers I took the launch pad as receiving device and configurred one of my devices as transmitter. I did a simple measurement of Rx power levels to get the antenna diagram. The launch pad has got an optimized antenna with a table of power levels corresponding to rssi values inside smart rf tool.
Now here comes my question I need your help to understand: RSSI values are documented everywhere to be the 2s complement of an integer value standing for a power level. Does the RF core really do a power measurement on that? Or is it expecting a perfectly optimized antenna to do a power level measurement by a simplified voltage level measurement? What about the other direction? If I want to send with e.g. 1dBm how to manage this? I would try to find out the transmitting power level by try and erroring the levels on my module value by value and see what the launch pad is receiving as power level then.
Am I on the right path of the force?
Kind regards
Markus
