CC1120 configuration no tx

Avi W
Expert 1345 points

hello,

I've followed Siri configuration from this link. 

It is working very well until I changed them to a state where there is no SNIFF (continuous  RX).

I needed to change the configuration & I guess I did somthing wrong since it seems that my board doesn't Tx any more.

The following is based on the Sniff_Mode_RX.xml file, please advice what am I doing wrong? 

I only need to be able to use "Packet Rx" mode from smartRf & to receive the packets from a device configured by siris' Sniff_Mode_TX.xml than to parse some data & Tx that again.. 

//siri configuration: 915MHz, rx filter:125KHz, symbol rate:62ksps, deviation:20.019531KHZ ,Tx: 4 dbm

    Hi

    Unfortunately it is a bit unclear to me what the problem is. You have said that you have changed my original settings and after you changed them you are not able to transmit anymore.

    I have gone through the settings you say is my original and compared them to your settings.

    Most of the changesare are don’t care in TX or do not change anything other than packet format, output level etc:

    SYNC_THR changed from 0x08 to 0x0B

    Number of preamble changed from 3 to 12

    CS threshold changed from -90 to -77 dBm

    RCOSC off instead of on

    EVENT0 0 instead of 0x2F

    Chang in TERM_ON_BAD_PACKET_EN and output power

    There are two settings that you should not change:

    Turning on the auto calibration (this is stated in the errata note)

    Why have you changed a bit in XOSC2 that are marked as reserved?

    How do you know that you are not transmitting anything? Are you checking with a spectrum analyzer or are you just assuming so because you are not receiving anything? What do you do with your receiver? Are you using SmartRF Studio or your own code? Are you using RX Sniff mode or regular RX mode?

    I think it would be easier to help you if you were trying to explain what you are trying to achieve instead of just saying that you need to change settings that are working and now it is not working anymore :-)

    Siri hello,

    Thank you for the replay.

    I didn't change the settings myself I've used the smartRf to load your  configuration (Rx sniff) & changed to packet Rx + changed the number of preamble bits. 

    Hence the XOSC2 & SETTLING_CFG.FS_AUTOCAL are both market ONLY since the smartRf tool set it up when moved from your sniff configuration to the Packet Rx.
    So are all the other changes they are a direct result of the switch from your Sniff configuration (XML) to the Packet Rx using the smartRf tool.

    What I'm trying to achieve is to have a set of 3 configurations (working = valid RSSI readings + transport of data is OK):

    1. Unit A: they only do Tx according to the smartRf configuration for packet Tx (12 bytes preamble + 915 mhz + 4GFSK + Symbol rate 62ksps ).
    2. Unit B: they do Sniff Rx + packet Tx (12 bytes preamble + 915 mhz + 4GFSK + Symbol rate 62ksps ).
    3. Unit C: they do Packet RX and packet Tx (12 bytes preamble + 915 mhz + 4GFSK + Symbol rate 62ksps ).

    What do we need?

    • We need that unit type A could talk to both Units type B & units type C.
    • We need that unit type B could talk to units type C.
    • We need that unit type C could talk to units type B.

    For your convenience I've attached all xml of your original Rx sniff & the Packet Rx of the smartRf tool.
