Error in Indoor channel model #2

Closed kelsayed closed 4 years ago

kelsayed commented 4 years ago

I am running the Indoorv1 channel model. I use the following command ./bs_2G4_phy_v1 -s=trial_sim -D=2 -sim_length=5e8 $@ \ -defmodem=BLE_simple -channel=Indoorv1 -argschannel -RiceK=1.5 -speed=2.5 -preset=Huge3 -at=-55 -ds=30 \ -exp=2.0 -dist=../components/ext_2G4_channel_Indoorv1/test/data1/trial_case_1.matri

I get the following error p_2G4: ERROR: (src/channel_2G4Indoorv1.c:380): Unknown modulation type 32

When I comment line 388 bs_trace_error_line("Unknown modulation type %u\n", ModulationType); and replace it with BW = 1*samplesPerMHz; //FixThis The simulation continues gracefully but I am not sure why this occurs or if this fix breaks the channel model. I don't like this hack. The modulation type needs to be properly selected before reaching this function.

Here is the log which occurs with other Zephyr NRF samples as well. Could you have a look or tell me if some of my parameters are wrong.

Fix by rstoica in https://github.com/BabbleSim/ext_2G4_channel_Indoorv1/issues/1 is perfect. Will close this now.
