In zephyr,i use direction rx and tx,in tx there a error code (-134),but i can't solve it,this problem occur in ncs direction.where is the problem?

[swz_nordic]

I use the zephyr version 3.0.9,when i build the hci_rpmsg project,it have serial error.then i chnange the onfigruation by  add some new definition.

I add some configurations to nrf5340dk_nrf5340_cpunet.conf files which is in C:\Users\Administrator\zephyrproject\zephyr\samples\bluetooth\hci_rpmsg\boards.

CONFIG_BT_PER_ADV_SYNC=y

# Limit number of possible connection to decrease memory usage
CONFIG_BT_MAX_CONN=1

# Required to enable BT_PER_ADV_SYNC_MAX
CONFIG_BT_PER_ADV_SYNC=y
CONFIG_BT_OBSERVER=y

CONFIG_BT_CTLR=y
CONFIG_BT_LL_SW_SPLIT=y

CONFIG_BT_CTLR_ADV_EXT=y
CONFIG_BT_CTLR_SYNC_PERIODIC=y

CONFIG_BT_MAX_CONN=1
CONFIG_BT_EXT_ADV=y

then i build the rx and tx ,in putty teminator,there is a error.

Starting Direction Finding periodic advertising Beacon Demo

Bluetooth initialization...success

Advertising set create...success

Update CTE params...failed (err -134)

I try to solve the problem by all kinds of way to,but it don't matter.where is the problem ?or do the procedures have problem?

Hello,

I'm somewhat confused. What version of nRF Connect SDK are you working on? 

Have you tested with a standard sample from the nRF Connect SDK v1.9.1 e.g. nRF5340: Multiprotocol RPMsg

Kind regards,
Øyvind

[swz_nordic]

Yes，thanks for your reply.i use the zephyr project. as zepyer describled.I don't make a try about nRF5340: Multiprotocol RPMsg.

I use NCS 1.9.0 for my project,but it have the error -134.I use the diffrent boards to flash this example,unforchunately,it has the same err.may it be your design problem.do you have a try?

[Øyvind]

Thanks for clarifying. nRF Connect SDK (NCS) v1.9.0  uses Zephyr v2.7.99. 

C:\Users\Administrator\zephyrproject\zephyr\samples\bluetooth\hci_rpmsg\boards.

This is the stand alone version of the Zephyr Project, while NCS should be installed (using Toolchain Manager) under e.g. C:\Users\Administrator\NCS. Note that we do recommend installing NCS to a shorter path i.e. C:\NCS, or similar. 

 

I add some configurations to nrf5340dk_nrf5340_cpunet.conf files which is in C:\Users\Administrator\zephyrproject\zephyr\samples\bluetooth\hci_rpmsg\boards.

As stated in the NCS Bluetooth: Direction finding connectionless beacon:

To build this sample for nRF5340 DK, with angle of arrival mode only, add content of overlay-aoa.conf file to child_image/hci_rpmsg.conf file.

This is referring to nrf\samples\bluetooth\direction_finding_connectionless_tx\child_image\hci_rpmsg.conf

but it have the error -134

Error -134 can be found in errno.h - e.g. zephyr\lib\libc\minimal\include\errno.h, which states:

#define ENOTSUP 134         /**< Unsupported value */

Please verify your configurations and let me know if this helps.

Kind regards,
Øyvind

I know your meaning,but there is a some diffrent bettwen nrf and zephyr.

The zepyer has no child _image,we should use hci_rpmsg as network core,i  build  the network core and apliacation cor in C:\NCS\v1.9.1\zephyr\samples\bluetooth\hci_rpmsg and C:\NCS\v1.9.1\zephyr\samples\bluetooth\direction_finding_connectionless_tx .

but there is no output .

*** Booting Zephyr OS build v2.7.99-ncs1-1  ***

in nrf, there is the same as previous.err -134.

besides,i alone install zephbyr enviroment, but now i can't use SES IDE

do you know this problem?

Please use the samples found in under C:\NCS\v1.9.1\nrf\samples, as stated in our documentation.

Bluetooth: Direction finding connectionless locator

nRF Connect SDK is based on the Zephyr project. Please install the nRF Connect SDK and focus on its environment. The Segger Embedded Studio is bundled with the Toolchain Manager found in nRF Connect for Desktop. Note that from version 2.0.0 of NCS, the VS Code extension is recommended.
