direction_finding_connectionless_tx - MPU problem/stack

[Avi]

I get error about MPU error stack size while trying to run the example from ncs v2.7.0 on nrf52833dk

I was able to build correctly and I see in the log file that it gets error on MPU for some problems with the cache 

I have not made any changes to the code

I am trying to transmit AOA and receive it on my UBLOX AOA antenna B10.

I was able to run UBLOX code example on nrf52833dk and it works

Thanks

Avi

Hi

My guess for why you don't see it on the UBlox antenna is that there is some filter on the receiver side set to only pick up and accept transmissions from UBlox devices, so you need to find out what filters it is using. UBlox should probably know what these are. Also, do the UBlox code also work in a connectionless setup and don't connect to the device?

Best regards,

Simon

Hi

I am using the same nrf52833 device for both the UBLOX code and the code from Nordic. So it is not a "UBLOX device".

As for the UBLOX code, I am not aware of any filter.

The UBLOX code is provided at: https://github.com/u-blox/c209-aoa-tag

It is a connectionless transmission 

In UBLOX code, I get also a eddystone transmission. Is it also part of the Nordic code?

Thanks
