How to get started with the EZR32HG Wireless Starter kit (SLWSTK6241A)
Hi Sebastian,
Show more
It looks like some Application Notes (as well as the example projects) are filtered out even if you selected an EZR32 kit, though the documentations and the sources are part of the SDK (I think, you know it, but if you have the default installation folder, you can get the resources at C:\SiliconLabs\SimplicityStudio\v4\developer\sdks\exx32\vXXXX\an). You can get the documentation, if you click on the checkbox on the Application Notes popup window's left bottom corner: and the projects can be imported (as delu suggested) by navigating to the AN's folder: Best Regards, |

No examples on simplicity studio 5 for SLWSTK6241A
Hi Felipe,

Thank you for reporting this issue! Sorry, when I checked it, I was able to create examples using 32-bit MCU SDK v5.9, and I wasn't aware that the examples for EZR32 parts are intentionally removed from SDK v6.x. You can still install the earlier version of the SDK or you might use Simplicity Studio v4. Best Regards, Bence |

UPDATE: The ezradio_ examples, among others, were removed from the 32-bit MCU SDK 6.0.0.0 according to the SDK's release notes. You can still install the earlier version of the SDK or you might use Simplicity Studio v4. Best Regards, Bence |

Is it possible to set a minimum threshold for Rx RSSI?
Hi Ratin,

According to internal discussions the detection scheme will not be improved/optimized further: we set such a low detection threshold in exchange for sensitivity gain. At last, the false detects can be filtered out by using CRC. Best Regards, Bence |

You should install (and then select) 32-bit MCU SDK, as the examples for EZR32 are part of that SDK. Best Regards, Bence |

RAIL_RxDataSource_t::RX_DEMOD_DATA - what is exactly the receiver output?
Hi Asdf asf,
Show more
I apologize for the delay here! Although, the scale of the 8-bit signal is determined by the filter's bandwidth, you should not calculate it: we recommend rather to measure it with a particular configuration and create your custom slicer based on your measurements. Thank you for finding the "typo" regarding the oversampling rate: the AN971 is the correct one in strict sense (however, you can config even higher than 10 oversampling rate by increasing bitrate). Best Regards, Bence |

I / Q data in efr32fg13
Hi Nata,
Show more
I'm sorry it took so long to response! Unfortunately you couldn't bypass the input filter. The bandwidth is ~1/4th of the IQ sample rate, so can set up 36 ksps IQ sample rate with ~9 kHz BW, or you can configure 25 kHz BW with ~100 ksps IQ sample rate. Then you can decimate the oversampled data by a custom decimator implemented on the other processing system you have. Best Regards, Bence |

I / Q data in efr32fg13
Hi Nata,

Could you please detail what did you have now (sharing an .isc file might be the best) and what is your request? What do you mean by the target (25 - 28 KHz) bandwidth, and how do you interpret the (36 KHz) IQ sample rate? Do they refer to the Acquisition Channel Bandwidth/Actual Bandwith and the Actual sample frequency entries of the generated log file? Would it be feasible only to have the IQ sample rate as a radio configuration design constraint and have a custom digital filter implemented on the processing system? The following forum topics discusses similar cases, you might visit them for further information: https://www.silabs.com/community/wireless/proprietary/forum.topic.html/custom_slicer_fordemodulation-efr32-Vdxh https://www.silabs.com/community/wireless/proprietary/forum.topic.html/iq_samples_and_samplingrate-oSk2 https://www.silabs.com/community/wireless/proprietary/forum.topic.html/question_about_rfparametersandrxdemoddata-p3j2 https://www.silabs.com/community/wireless/proprietary/forum.topic.html/iq_radio_mode-QAgx Best Regards, Bence |
