We are developing the RF module with CC1120 plus CC1190.
Our two modules can be communicated with each other in easy mode(one is transmitter, another is receiver)
But, Our transmitter can not send the packets to receiver in expert mode.(sent packets: 3, packet counter was counted)
in expert mode,
1. i did double click the defualt manu(868MHz, Bit rate: 1.2kbps, 2-FSK, RX BW: 25KHz) / Transmitter & Receiver be set with same.
2. i pushed the start button.
3. The transmitter could send the just three packets to receiver. (sent packets: 3, not increased)
please let me know the solution.
And then, i pushed the stop button.(message was displayed as follow: sending of packets failed)
i don't know why transmitter can not send the just three packets.
It sounds like you don't have the latest firmware on the TRXEB. Which version of hardware / software are you using?
--PS. Thank you for clicking Verify Answer if this answered your question!
We designed the DK board with CC2511 to interface with SmartRF studio7 like the TRXEB V1.5.
Firmware revision on SmartRF studio7 window is 0016.
But your DK board firmware version is 0019.
I did download the latest version.(V1.6.1)
what's difference between them?
please let me solution.
The parts to interface with CC1120 is the same with your DK board.
The other part is different.
Please download te newest version of Studio here: http://www.ti.com/tool/smartrftm-studio
The method of sending/ receiving packages has changed in the newest releases of Studio and the error message you get get is typical when the MCU does not receive a signal from CC1120 that the package is sent. This also requires that the IOs are used in the same way as on the EM/ TRXEB.
I did download the program and installed.
The message to upgrade the firmware version is displayed, and then i pushed "yes" and "done".
After being finished the upgrade, turn off the power and turn on the power.
The firmware version is the same with the previous it. (Firmware revision is 0016)
Please give me a guide in more detail.
OK, i solved the problem to upgrade firmware revision.
But, i could not send the packets more than just three packets.
i could send the packets in easy mode but not in expert mode.
i want to test in expert mode.
Please give me solution in more detail.
The TrxEB packet handler uses two CC1120 GPIO lines to handle packet RX (GPIO0 and GPIO2) and GPIO2 to handle packet TX. These lines must be connected.
In expert mode, do you send the same packet as in Easy mode, i.e. you switch to Expert mode without changing any settings?
The TrxEB packet handler uses the PKT_SYNC_RXTX signal from the CC1120 to get notified about when a packet has been sent. If you have a sync word length of 0 (zero), the PKT_SYNC_RXTX signal will never go active and the packet handler will not work (You see 3 packets sent because of internal buffering on the TrxEB).
Thank you for your reply.
First, GPIO 0 and GPIO 2 is connected to CC2511 on our DK board like the TRXEB.
Also, i did carried out the "Continuous Rx test" in expert mode and then did test the demodulation signal entering the Signal generator.
So, i think that GPIO 0 and GPIO 2 function works well.
in expert mode, i did click the default menu(868MHz, Bit rate: 1.2kbps, RX BW: 25KHz) provided the Smart RF software.
And then, i pushed the start button in "Packet Tx" tab.
But, this works well on the TRXEB even if i did the same sequence on our DK board.
if i clicked the "link bypass, 868MHz" and then push the start menu in expert menu, does it woks?
I don't know the correct selection to do the packet test in expert mode in more detail.
Please let me know the sequence or method to do the packet test in expert mode.
I found that Sync_mode is set to 0x05. so, i think that sync word is not zero.
