EZR32LG Fail running Simple TRx example

Hi,

 

I'm running Simple TRx example (without changes) under EZR32LG, but some problems are happening.

 

First:

When Board 1 and 2 are changing packets, apparently the sequencwe is broken, Board 1 sends the correct sequence but Board 2 receives an old packet. (attached file 1)

 

Second:

Incorrect received data as showed in attached file 2. I was hopping, in that case, a CRC error during transmission.

 

 

Best regards,

Denis

Hi Denis,

First:   I have checked, the program run normally, and couldn't reproduce your question. I created the project based on Gecko SDK v5.0.0.

Second:  Which demo code did you test about frequency hopping?   The simple TRX project we provide doesn't contain frequecy hopping.

Hi Denis,
When you read the whole demo code, you'll find if there's a crc error, "-->Pkt  RX: CRC Error" will be printed on the LCD screen.
But, the screenshot you sent is not, it seems the received packet passed with crc checking.

SO, I think there should be some problems about your code with the board.
What's board do you use for testing?  Is it a standard WSTK from silabs?
Could you send your whole source project to me for a further analysis?

Yongsheng
