Hello Experts,

I am trying to receive some TPMS sensor data on CC1310. Following are the RF profile of the sensor:

F nominal: 434.1 MHz
F Accuracy: -50 - 50 KHz
F Offset (ΔF): 50 KHz (min.), 80 KHz (Nominal), 110 KHz (Max)
RF Power @3m peak: 70 dBuV/m (min.), 75 dBuV/m (Nominal), 77 dBuV/m (Max)
Logical Level: H = Fnominal+△F/2 KHz and L = Fnominal-△F/2
Baud Rate: 19200 bits/s
Encoding: NRZ (with an extra start (0) and stop (1) bit)
Transmit Time = 5.73 us

The sensor sends data in form of packet, the packet structure is as following:

K0 + Frame + K1 + Frame + K2 + Frame + K3 + Frame
where K0-3 are separators for frame
Each packet hase 4 identical frames.
Each Frame lenght is 11 bytes, including first 2 bytes as the sync word.

I have tried to receive the data using the SmartRF Studio 7 (version 2.10), I have configured the parameters as per the sensor RF profile. But I am not able to get any understandable data. I have attached the SmartRF config file and SmartRF settings file I have used.

Apart from this I have tried to sniff the data using the Smart RF Packet Sniffer 2 with reference of

But I am not able to get any packet from sniffer with 434.1 MHz frequency.

My Questions:

Did I have any mistake in configuring the SmartRF studio with reference of sensor RF profile ?
Why am I not able to sniff any packet ?

Please help me identify the correct RF setting of CC1310 Radio to receive the packets from sensor

Hi Ravi,

Assigning an expert to comment.

First of all, the CC1310 required preamble in front of the sync word. From what you describe, it sounds like the two first bytes in the packets are the sync word, and that there are no preamble. Also, there are no support for removing start and stop bits from the data stream, so this must be done from the application.

To be able to verify that you are able to receive anything from an RF point of view, I would recommend that you enable serial mode in the cont. RX tab in SmartRF Studio and that you look at the raw data on DIO_7 to verify that you are able to receive the data from the sensor.

Hi Siri,

What will be the differece between data received from continuous Rx and Packet Rx ? and

Can I read the serial output data from XDS110 Class Application/User UART listed ? I will try with the continuous Rx and will let you know.

0 Siri over 4 years ago in reply to Ravi Chovatiya

In cont. mode the radio is not looking for any sync word etc. It simply output the raw data it receives on the air to a pin. You cannot read these data over uart. You simply need to connect a scope or logic analyzer to the pin and monitor it to see if you receive what you think your sender is sending.

If you can see the data, then you can set up the radio in normal mode to look for sync word etc. The reason I suggested this is that you first need to check that your RF settings are OK so that you are actually able to receive the data. When that is confirmed, you can start figuring out how the packet engine needs to be configured to be able to receive the packet in the FIFO.

Thanks Siri,

We have enabled Continuous Rx (in serial mode) & tried to capture Data packets from DIO7 pin on MDO-3024. But, there's a random/noise Data packets coming out from DIO7 even when nothing Broadcasted by Sensors & we're unable to filter-out valid Data packet on DSO.

Is it expected that DIO7 sending out noise data too? If yes, How to filter noise from Actual Data packets for decoding?
In RFstudio's continuous Rx (serial mode) operation, whether it also depends on other RF settings? (i.e Set in CMD_FS and CMD_PROP_RADIO_DIV_SETUP)

Thanks and Regards

There will always be some noise on the air, so when using cont. RX you will see noise on that pin even if your transmitter is not sending. I would recommend that you do a test first where you use 2 CC1310 devices first, and transmit packets with one device and receives with the other, using SmartRF Studio.

After verifying that this is OK, you can set your receiver in cont. RX and monitor the DIO. You should be able to recognize the packet.

When this is confirmed you can try normal mode. Your RF settings must be correct to receive something both in normal mode and serial mode.

Hi Siri,

Appreciate your quick response,

Meanwhile, we perform an experiment to test Tx-Rx using 2 CC1310-launchpad kits by SmartRFstudio and try filtering/decoding DIO7 data frames,

Can you please verify & confirm our RF settings are CORRECT for Sensor Specs? & we must receive actual Raw Data based on Sync_Word.

*********SmartRFstudio Parameter summary******* (For all parameters, please refer 2727.smartrf_settings.c file attached above)
// Frequency: 434.10001 MHz
// Deviation: 50.000 kHz
// Fixed Packet Length: 30
// Max Packet Length: 11
// Packet Data: 255
// RX Filter BW: 98 kHz
// Symbol Rate: 19.20013 kBaud
// Sync Word Length: 16 Bits
// TX Power: 15 dBm
// Whitening: No whitening
****************************TPMS Sensor Specs**************************
// F nominal: 434.1 MHz
// F Accuracy: -50 to +50 KHz
// F Offset (ΔF): 50 KHz (min), 80 KHz (Nominal), 110 KHz (max)
// Baud Rate: 19200 bits/s
// Encoding: standard NRZ
// Each frameTime = 5.73 ms

The TPMS sensor broadcasts a packet & each packet contains 4-frames, like:

K0 + Frame + K1 + Frame + K2 + Frame + K3 + Frame (here K0-3 are separators between frames)
All 4 frames are exactly same Data
Each Frame length is 11 bytes (first 2 bytes:sync word , 7 bytes:payload, last 2 bytes:CRC)

******************************************************************************

Also, can we get directly NRZ decoded Data Packets in SmartRFstudio by some RF settings?

Thanks & Regards,

Ravi

Hi Siri,

As per your suggestion, with TWO EVK setups as Tx & Rx mode.

We have captured the waveform of Known Data on DIO_7 (transmitted - ff ff ff ff ff ff ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 (48 bytes with, preamble=55 syncword=5555). Waveform picture as below.

But, when we Transmitted actual Sensor Data bytes (i.e. 5A AA 78 23 14 14 64 64 20 0D 65) from Tx-EVK, we are unable to capture waveform from DIO_7 pin due to continuous noise. We tried multiple trigger settings & single instance signal capture settings of our spectrum Analyzers.

Can you please guide us, that how can we capture the correct Data Waveform? or reduce continuous noise on the DIO_7 pin of Rx-EVK.

Thanks & Regards,

Ravi

Hi Ravi.

Do you use SmartRF studio to get the waveform on pin 7? Can you show a screencap of the noise you get on pin 7 when transmitting with sensor data?

Hi Vegard,

Nice to e-meet you & thanks for response,

Yes, we are capturing Data Waveform from DIO_7 pin of cc1310 Launchpad EVK, using SmartRFstudio's Continuous Rx serial mode enabled feature.

You can clearly see the constant Noise generated from DIO_7 & it's very difficult for us to identify/differentiate Sensor Data out of it. Moreover, once Sensor pressurized, it broadcasts Data packets every few seconds..

Hi Ravi.

It seems like the picture didn't get uploaded properly, can you try again? For the first waveform. This is with the same setup as when transmitting sensor data, except that the transmitted data is different?
