Unable to pair DWM1000

Rituraj · ‎2024-10-17

I am trying to use DWM1000 for ranging as well as communication but I am unable to do it . I debugged the code and Know that Initiator is sending data but is not being heard . The Rx buffer in responder is geting updated by random values.
I have attached the code to both here . If anyone could help it will be very helpful.

I tried everything . ALL I knbow as of now is that there is an issue due to timing and thus the devices are not getting connected

I am working with DWM 1000 and STM32f429zit and stm32g491ret which I have used and worked fine for data transmission I want to use the same for the ranging purpose . At th initiator tx_count increases continously as indication of data being transmitted on other hand at responder the rx_buffer is already full with garbage and this stops the responder for completeing the further . If anyone has worked with this in partivcular or knows a way to get rid of the issue kindly respond ASAP.
I have attached both codes to this mail.

Again, that does not confirm that anything is actually been transmitted to the air.

Don't Qorvo provide tools to "sniff" what's actually being transmitted to air?

The best place to find such people would be on the device manufacturer's forum:

I already tried to get answers on Qorvo forum but I am getting no response at all.

A Sniff code has been provided but its for a BLE sniffer and I will need to start working on nrf sdk to utilize that.
I checked using a dummy antenna and oscilloscope . I know the wave exists and is being transmitted as I checked on DSO but again I need it to be recieved on DWM1000 module

So have you contacted Qorvo support?

Rituraj · ‎2024-10-23

yes , did that too . No response till now

Do you have a distributor to help?

Do you have the Qorvo dev kit?

I would strongly recommend to always start with the manufacturer's own dev kit - especially when you're unfamiliar with the part.

No dev kit .

I debugged it for every possible way. I know for sure that transmission is being done as I can read the SYS_ STATUS but on the responder end even this changes very rapidly and according to what I compared there is and Interrupt that is preventing operation.

Again, I would strongly suggest that you get one - then you have a known-good starting point.

You are also far more likely to get support on that than on some unknown custom setup.
