Hi Michel:

Hi Michel:

It is possible to get to extract RX IQ data on the DA14681 device, not DA14580.

The IQ data can be then post-processed.

Additionally, capturing of RX IQ data on DA14681 device is NOT supported in our official SDK.

It is supported on special test firmwares.

What is your application ?

Thanks,

TR_DIALOG

Hello

Thank you for your fast reply.
I am designing a measurement device to evaluate impacts of external interference on BLE.

Hi Michel:

Hi Michel:

Are you developing a commercial product?

Also, have you looked at DA14681 to determine if this fits your product's requirements ?

Initially you had asked the question in the context of DA14580.

Thanks,

TR_DIALOG

Hello,

Hello,
Yes, it aims to be a commercial product and for the moment it is at the level of proof of concept design phase.
尽管DA1 DA14681符合我们的要求4580 would be sufficient.
May we have a contact person at Dialog to discuss directly because of NDA?

Thx

Hi Michel:

Hi Michel:

I will check with the team about availability of this software. Since this is not a released software, that means it will have some limitations.

I will update the ticket once I hear back. Most likely next week.

Thanks,

TR_DIALOG

Hello TR_DIALOG

Hello TR_DIALOG

Any news about capturing RX IQ data on DA14681 (or DA14585)?

Thanks,
Michel

Hello TR_DIALOG

Hello TR_DIALOG

I'm interested in evaluating this functionality as well for our indoor location technology.

Hi camilor,

Hi camilor,

Currently none of the devices support IQ data access out of the box, currently there are no APIs which could be used in order to obtain that, at least at the moment.

Thanks MT_dialo

Hi,

Hi,

I understand that the Ripple RF IP is able to provide it, along many other parameters that can be valuable for our indoor location technology. We are used to work with radio level access, having it with other suppliers ICs (Nordic and icyTRX). We are evaluating our options for a next generation of our technology and I'd like to include Dialog in the evaluation.

It is possible to have access to the special test firmwares that makes these readings as a base for our evaluation? Or is it possible to have access to the RF detailed documentation?

Best regards

Hi camilor,

Hi camilor,

Sorry for the late response, i was checking with the team, unfortunatelly, currently there is no support for this or accessing RF documents outside of Dialog, especially on the 58x family.

Thanks MT_dialog
