CC1310: Receive nothing using 433M@1Mbps with RF_cmdPropTxAdv & RF_cmdPropRxAdv

will wang43
Expert 1205 points
Part Number: CC1310

Hi

I'm tring to use CC1310 to do a test, as below:

1.PAYLOAD_LENGTH is 4000

2.Using 433M@1Mbps with RF_cmdPropTxAdv & RF_cmdPropRxAdv

3.PacketInterval = (uint32_t)(4000000*0.5f);  It's 500ms.

But the receiver cannot receive anything at all. I check transmitter end with spectrum analyzer, and I can see spectrum correctly, this indicate that data has been send out correctly.

So I changed settings like below:

1.PAYLOAD_LENGTH is 30

2.Using 433M@1Mbps with RF_cmdPropTx & RF_cmdPropRx

3.PacketInterval = (uint32_t)(4000000*0.5f);  It's 500ms.

Now they can communicate with other correctly.

And further test as below:

1.PAYLOAD_LENGTH is 4000

2.Using 433M@50Kbps/500Kbps with RF_cmdPropTxAdv & RF_cmdPropRxAdv

3.PacketInterval = (uint32_t)(4000000*0.5f);  It's 500ms.

They also communicate with other correctly.

So I guess if using 1Mbps@RF_cmdPropTxAdv & RF_cmdPropRxAdv has some problems or somewhere should be modified?

Thanks!

    Hi,

    it's not possible to use the proprietary PHY at this symbol rate. Sorry, the maximum is 500 kBd. There is a semi-official high-speed PHY for the CC1310. You can find it in the rfPacketErrorRate example. But this mode has only been specified for 868 Mhz. It doesn't work at 433 Mhz.

    Hi Richard W

    Thanks for your reply.

    Actually, this 1Mbps configuration is provided by TI about last year, as attached.And the 1Mbps is datarate, not symbol rate.

    You mentioned:it's not possible to use the proprietary PHY at this symbol rate.But I did range test about 1Mbps@433M & 868M using RF_cmdPropTx & RF_cmdPropRx, it worked OK!

    So, How to explain this?

    Thanks!

    Hi,

    you are not running the generic FSK PHY, but you are running kind of a BLE-alike PHY with the proprietary commands. No guarantees about the performance. However, using CMD_PROP_RX_ADV and CMD_PROP_TX_ADV, you should be able to transmit large packets. But keep in mind that 4000 bits is very long. Bit errors will likely occur and the packet will not be received. Especially in a crowded band like the 868/433 Mhz band.

    Does it work with the advanced commands if you transfer packets of about 300 bits?

    HI  Richard：

    1.The 1Mbps settings was provided by TI Shanghai office about last year.

    3.But modify PAYLOAD_LENGTH bigger than 1000, then test 1Mbps@433M communication, it failed!

    A question on the side: Why do you want to use this large packets? In theory this should give you larger throughput but the probability for bit errors in a 4000 byte packet start to be significant meaning that you probably have to do a lot of re transmit which reduce the throughput in the end.

    Hi TER:

    Thanks for your reply.

    "Why do you want to use this large packets?"----Because my customer's product is ESL, and the gateway will send 100KByte data to node at 1s.

    So I need to test CC1310's throughput at 1Mbps@433M.

    And as what I said,

    I tested 1Mbps@433M with PAYLOAD_LENGTH, it worked OK!

    But modify PAYLOAD_LENGTH bigger than 1000, then test 1Mbps@433M communication, it failed!

    can you pls help to check if there is some problem?

    Thanks!

    Could you post the full CCS project you are using for your tests?
    --
    Could you provided me with more details on the application?
    - You write that the gateway will send 100 kB of data to the node. Is this 100 kB to one ESL? If it's to several ESLs I would assume that the data to each ESL are different and you need to send a different packet to each ESL?
    - As I wrote the probability for bit errors increase with large packets. How will the system handle bit errors?

    Hi TER：

    Thanks for your reply.

    PERTest-RXAdv.rarPERTest-TXAdv.rar

    My project is build by IAR 7.8.4 with CC1310 SDK Version tirtos_cc13xx_cc26xx_2_21_00_06, the project is based on "rfPacketErrorRate".

    1.As you said, the gateway will send 100 kB of data to several nodes.

    2.My customer is just evaluating whether CC1310 is fit to their application. So I guess they might do re-transmit when bit error occurs.

    3.I will communicate with my customer about the issue that you mentioned before.

    At last, I want to know that when CC1310 1.5Mbps@433M will release? And can you tell me if  my 1Mbps@433M configuration is the official configuration or not?

    Thanks!

    Hello Will,

    The patches needed for 1.5mbps mode on CC1310 are included in the latest SDK release and we are working on adding this mode to SDK examples. In the meanwhile, we are working on providing settings needed to implement this mode in the next week. However, this has been characterized at 915MHz and only tested for functionality at 433MHz under typical condition.

    Regards,

    Will: Any reason you use an old version of TI-RTOS? I don't have it installed so it's not straight forward to test the code you provided. The settings SVS wrote about will also be provided for the latest SDK.

    Hello,

    Any update on the settings/examples to implement 1.5mbps on the cc1310? Also, where in the rfpacketerrorrate is the setting for the data rate?

    Thanks

    Hello,

    To add 1.5mbps 4FSK mode to the PER test, add the following settings to the smartrf_settings_predefined.c file in the PER project and use the HS API (same as HS mode) to transmit and receive. There are minor changes needed to add this mode on the menu and display for PER test. At 433MHz, it is recommended to program the device at 1mbps instead of 1.5mbps and reduce the deviation. The following settings have been tested at 915MHz.

    Hi SVS：
    Thanks for sharing.
    I tested 1.5Mbps with 868M Module, but I cannot receive anything.
    As you said," The following settings have been tested at 915MHz", so have you test 868MHZ?
    And, you said " At 433MHz, it is recommended to program the device at 1mbps instead of 1.5mbps and reduce the deviation", Does it means 433M don't support 1.5Mbps datarate?
    Thanks!

    Hello Will,

    There was an error in overrides on my first post which I corrected soon after. Please re-check the overrides and let me know if you still see issues.

    It should work at 868MHz as well.

    At 433MHz, under typical conditions, it is functional. However, we have not tested it across corner conditions and optimized the performance in this band.The synthesizer will be operating close to the limit at this frequency band with 450KHz deviation (used at 1.5mbps datarate). It is safer to operate at lower datarate and deviation settings at 433MHz band to avoid issues across different operating conditions.

    Hello Will,

    The edited settings are in my  previous post.

    Also, please find attached files that I modified from the packetErrorRate test for CC1310 in the latest SDK release to include 4FSK mode. After importing the example project from SDK, if the files in the attached folder are used to replace the files in the project, 4FSK mode should be added to the example.

    Let us know if this helps.

    I have tested 868M&915M with 1.5Mbps datarate,and it works fine.
