How to perform continuous output with LORA modulation enabled. #41

Closed reissjason closed 2 years ago

reissjason commented 3 years ago

The Sx1301 HAL utiliities have util_tx_continuous for CW, LORA and FSK modulations. The test_loragw_hal_tx utility can perform a continuous CW but only output LORA and FSK in packet mode. The certifications lab is requesting a 100% duty-cycle signal to measure Power Spectral Density.

You can use test_loragw_hal_tx, with a very long preamble size (65535). Used with SF12, it will last several minutes. This is how we simulate a continuous TX internally.

Thank you Michael, we will give that a try.

This works as described, thanks!
