我用WDS软件生成的配置。配置FRR A 存放 RSSI LATCH，并且 配置当SYNC同步字时锁存。当接受端收到包中断后使用函数si446x_frr_a_read 或si446x_get_modem_status 读取到的RSSI锁存的值均为0.
I'm developing an application with Si1060. Periodically I send some packet of byte through radio interface and all works fine. However, when the radio interface doesn't send any data the radio carrier go down.
I need that the radio carrier stays on when the radio part finishes the trasmission.
Can I do it?
how to set up the registers to get this behavior?
The EZR32LG330 and EZR32WG330 wireless MCUs both include USB modules.
Their datasheets both say that they come preprogammed with the bootloader described in AN0003.
However AN0003 says that devices that include USB support include a USB bootloader like the one described in AN0042.
Do the USB enabled EZR32 MCUs come with a USB bootloader?
I am using the ezr32WG and I am looking for the definitions of register of the ezradio. Where can I find a explanation of all #define that I find in ezradio_cmd.h?
Thank you for your help

I'm working on a case that has a limitation of system power consumption about 1mA, including mcu, RF module and control circuit. Is there any RF module(433MHz or 315MHz) can work under 1mA mostly receiving mode?
Please advise. Thanks.
I'm using the EZRadioPRO Eval Kit (WMB-930) with the Si4463 based Pico Bd. I'm starting to get a handle on the sample code generated by WDS. I'm comfortable with the LCD library, I now want to start displaying specific register values in the test code that I write.
Is there an easy interface to these registers? I would think I would have to call one of the functions from "si446x_api_lib.c"........i.e.;
void si446x_get_modem_status( U8 MODEM_CLR_PEND )
Si446xCmd.GET_MODEM_STATUS.CURR_RSSI = Pro2Cmd;
How do I call "....get_modem_status"?
Is the Struct/Array global?
Any examples would be appreciated.
I have a question about the 4FSK demodulation on the Si4362. I'm receiving a stream of Flex Pager data, which encodes using 4 frequencies around the carrier:
From the datasheet I see no way to configure the operation of 4FSK. Can the 4FSK demodulator handle these? Does it self-adjust somehow?
I have not selected a part yet as I'm not sure if the Si4362 4FSK is going to work for my app.
I flashed the range test example of my module from Simplicity Studio to the card. Packets are sent and received according to the range test graph and the packet receive total. However, the field indicating the RSSI in dBm and the % PER is always inactive. What configurations must I change to view these results?
Hi, can someone plz refer me to a short summary of ISM frequency selection?
Eg, why would i choose 868 Mhz over 950 Mhz? Why is 868 common? Why 915 Mhz?
I'm guessing one factor is local laws. What other factors, aside from laws, affect choice?
Is there one freq in the 800 to 1,000 Mhz range that's a best choice for an international product?
Only asking about the 800 to 1,000 Mhz range, plz.
How will the two scenarios differ, with regard to sensitivity, range, data-efficiency, power-usage, etc etc.
I base my design on "WES0134-01-4468CPSQ27F169-01" Silabs Design kit for a 169MHz@27dBm application.
In the BOM a NESG250134 npn SiGe transistor is present, but this component is obsolete.
Did someone find same problem? Any suggestion to substitute the transistor without changing resistor or capacitor around?
Thank you in advance.
Hi Guys, I used EZR32WG330 development kit to import unmodulated carries example and it is working fine. The same binary file downloaded into our own board but nothing happing.
what could be the possibilities?
I am working on implementing Automatic Frequency Hopping on the Si4463. I have a few questions:
1) There are for different settings for the automatic frequency hopping. Anyone have any recommendations on one they would recommend for the highest range. I will be using 50 channels.
2) I see a TX_HOP command in the API but it does not accept any parameters. Does this mean it will pull the frequency to hop to from the rx hopping table? If not, does that mean that I need to keep a table of the frequencies in my MCU as well in order to implement the tx frequency hopping?
3) Anyone have a recommendation of a psudo random frequency hopping table generator?
I'm trying to set up UART via USB using an EZR32WG evaluation board. With the range test example UART works fine but the code is not provided.
I found a help page and tried setting up an example project with the provided files but so far with no success:
I used an empty C-Project, the provided example files and a few added emlib files. I can compile and run the project but don't get any response from UART (I tried sending characters (CR-terminated)). I don't see constant string printf() output either. I'm using Simplicity Studio and hTerm.
In short: I'm looking for an example how to set up UART over USB with this kit.
