Hi,

I have the Flex Gecko(2.4GHz and 915MHz) and the 2.3.0.0 SDK. I am running the RAIL Test example. When I select from the Base radio profile the default PHY  {2450M 2GFSK 1Mbps 500K} the application works properly and I am able to use the various commands in the console. Whenever I try to select another PHY profile for example {915M 2GFSK 100Kbps 50K} the application is crashed and I can not type anything in the console. Is it supposed to work only for 2.4GHz PHYs?

Thanks,

Georgios

Hello,

In EFR32 getting started ( https://www.silabs.com/documents/public/quick-start-guides/qsg138-flex-efr32.pdf ) , in "Manually Compile and Flash" (page 27-28) it is described how to load application to memory.

But in the example it shows image of "ncp-uart-hw" example which is not mentioned anywhere in that section or before (but only later).

Is ncp-uart-hw project required in order to load application to memory ?

Another question, does ncp-uart-hw can interact with any host application ? How is it that it can interfaces with any host application ? What are the APIs between the project in host and the ncp project, which makes any host application to interact with ncp-uart-hw  ? 

Thank you,

Hello,

Does anyone knows the difference between 

"Commissioned Direct Device "and "wire replacement" examples ?

from documentation:

"Connect (SoC): Commissioned Direct Device: Demonstrates direct communication between nodes in range. The network parameters are commissioned by the application.

Connect (SoC): Wire-Replacement: Demonstrates point-to-point bi-directional direct or indirect communication between two nodes."

Thank you,

Hello,

Is it possible to add OTA bootloader to RAIL application ?

How should it be done ?

Thank you,

Hello,

How can we achieve manual hopping with connect ? 

Thank you,

ranran

We need to build a POCSAG transmitter.

Frequency: 868MHz

Modulaton: FSK.NRZ

Data Rate: 512bps / 1.2Kbps /  2.4 Kbps.

Channel spacing: 12.5Khz or 25Khz.

Thank you in advance. 

(This is my first time post question, not sure if i post in wrong place)

Hello,

We need to use flex gecko with tx ACK and manual hopping.

Can anyone please suggest between connect and rail ?

Thank you,

ranran

Dir Sir,

I tested same board and same source code on Si4463-B1 and Si4463-2A.

I fixed data rate by 2.4Kbps on 2FSK

Two board generally works.

When the Si4463-2A sends data and measures the completion time, it takes about 700ms, and Si4463-B1 takes about 70ms.

Why is there so much difference?

Hi,

I have the Flex Gecko and the 2.3.0.0 SDK. I am running the Sensor-Sink example. I want to use the network analyzer tool for this example but every time I start to capture I get a decryption failure message from simplicity studio. "At least one packet has been found which failed to decrypt. This often happens if you have invalid keys set in your preferences. Please verify your preset keys. " The same message appears even when the security is disabled or even if I restore default security keys under the preferences menu(windows->preferences->Network Analyzer->Decoding->Security keys). Any help will be great!

Thanks,

Georgios

Hi,

I am currently on the Flex 2.2.2.1 SDK programming an EFR32FG1P133F256GM48. When starting from the simpleTRX example the radio never gets initialised and stuck in the radioInit() function because the call railHandle = RAIL_Init(&railCfg, NULL); always return NULL to railHandle. railCfg is the default one from the example code (static RAIL_Config_t railCfg = { .eventsCallback = &RAILCb_Generic, };)

Does anyone know how to fix that or where to start digging through the code to start looking for the problem. Unfortunately step by step debugging doesn't give me any insight into where the RAIL_Init functions fails.

Thanks!

Hello,

I am trying to build connect or rail examples, but it keep fails rail.h missing and various similiar missing files.

I'm not yet connected to kit, but only installed packeges (only proprietry wireless, the thread package need kit serial).

Is it fails becuase of the thread package not installed ? Is it becuase the kit is not connected (and somehow the kit download more packages) ?

Where do we download connect or rail package is downloaded in the propritry wireless package ? Is so, why do I get the failure in build.

I use latest simplicity (v4) , windows 10.

Thank you,

Hi,

I have the Flex Gecko and the 2.3.0.0 SDK. I am running the Sensor-Sink example. Is it possible to set the Sink(coordinator) to send out periodic beacon messages so that the Sensor synchronizes with beacon and only communicates during the active communication period? If it is possible how can I do this? Thank you in advance,

Hi All,

I am using the ZETA 433 from RF Solutions, which implements a SI4455. I use a STM32F103RB (Nucleo 64 board) to send commands to the Si4455.  I have several questions.

First, is there a document to understand the responses sent by the module ? For example, when I send the command 0x01 (PART_INFO), I have the response "FF 11 44 55 00 00 0D 00 03 00", which is a good news. It means that the module correctly receives the command 0x01 because the beginning of the answer is 0xFF and send me its part info, but how can I understand these data ? I found another post on a forum saying that 11 44 55 means that the module is a SI4455, but no official document tells me that. For me, there is a lack of information concerning the response from the module.

Does I need to use WDS Software to program the module ? In the header file generated, there is big tab, but I can't find the "EZ_Config_Array". Is it possible to program the module without WDS software ? For example, in my program, I would like to change dynamically the channel of the module, what command do I need to send ?

Then, in the WDS datasheet, it is indicated that the software doesn't generate the same header file twice for a same configuration "due to the encryption method". What is the purpose of this "encryption method" ?

I am a little bit lost with this module. I would be very grateful if someone can help me.

Thanks.

I have bought Si4010 development kit including Rfsticker for si4355 and I've successfully downloaded and run both TX and RX with example programs.My intention is to modify  example code of rke_demo_2 and EZRADIO_SI4X55_1W_KEYFOB_DEMO to be able to do these in 433.92 MHZ:

A-By pressing the “button1” in transmitter only LED1 in receiver turns on for the all the time of “ button1” is being pressed and as soon as releasing the “button1” LED1 turns off.

B-By pressing the “button2” in transmitter only LED2 in receiver turns on for the all the time of “ button2” is being pressed and as soon as releasing the “button2” LED2 turns off.

C-Transmitter and receiver pairing and un-paring capability with SI4010 unique ID #

  -Receiver checks the transmitter (si4010) unique ID # and pairs SI4010 to SI4355 so just this transmitter will be able to connect to this receiver

  -Some sort of un-pairing process

I checked AN692,AN370,AN104,AN747,AN796,AN797 and used all example codes  for TX and RX in SI4010 Key fob demo kit in both key fob and RFstick platform and be able to turn on and off LED in receiver (by using WDS, IDE, KEIL-V5 and instructions).

I have multiple questions:

Q1:I don’t know where and how to find and see the SI4010 unique ID # in receiver side example program which is being send by transmitter to play with it and store it in memory in order to pair both receiver and transmitter.

Q2:I don’t understand this part of code in ReciverDemo.C in example si4355 code which checks something and turns on the LED1? 

if (RadioPacket.Flags&(1u << 2u))

Q3: Where is the description of ReciverPacket in program and how is packet  being stored in ReceiverPacket?

Q4: I know "u" means unsigned char and << means move bits to left but What does actually this part of code " 1u<<2u" work and how does it check the "Button1"  ?

Q4: How to get access to received "payload" in receiver side to compare with pre-stored value in receiver?

There are a lot of other functions in example code which I couldn’t find in all AN??? s.

Thank you for the help
