app_ZDebugB0.conf of nrf_desktop in NCS

[joe]

Hi all:

About with the nrf_desktop example in NCS ,

I would like to modify the CONFIG_BT_HIDS_MAX_CLIENT_COUNT to '2' ,

so I add below command at "app_ZDebugB0.conf"

CONFIG_BT_HIDS_MAX_CLIENT_COUNT=2

But when I use Serrger_Embeded_Studio to open project ,it always shows "create_nordic_project.py failed".

Could  I write this command at "app_ZDebugB0.conf"? or another file?

condition:

nrf connect SDK 1.7.0

board name:nrf52kbd_nrf52832

project: nrf_desktop

best regards,

Joe

Hi,

Could you select the 'OK' when this error occurs and show me what appears in the Output Console?

Hi PK:

please refer attached file.

When I select 'ok' ,the "error: cmake failed" was showed in Output Console.

because I want two host can connect to my device(not in the same time) ,I modify the CONFIG_BT_HIDS_MAX_CLIENT_COUNT to "2".

Hi Joe,

As you can see here,

warning: BT_HIDS_MAX_CLIENT_COUNT (defined at

value '1'. See

The device count assigned is still 1, which may be because you should also set the BT_MAX_CONN. You can refer here regarding the direct dependency.

What you can do is, enable the CONFIG_BT_HIDS_MAX_CLIENT_COUNT and also set the CONFIG_BT_MAX_CONN to 2.

Then try building and let me know how it goes

Kind Regards,

Hi PK:

thanks for your information,

I add the below commands into app_ZDebugB0.conf,it can solve the "create_nordic_project.py failed"

CONFIG_BT_HIDS_MAX_CLIENT_COUNT=2
CONFIG_BT_MAX_CONN=2

but It appears an error when I build the code.

It seems I can't set the CONFIG_BT_HIDS_MAX_CLIENT_COUNT or  CONFIG_BT_MAX_CONN to 2.

I try to  enable CONFIG_BT_HIDS_MAX_CLIENT_COUNT  ,so I add below commands into app_ZDebugB0.conf.

CONFIG_BT_HIDS=y
CONFIG_BT_HIDS_MAX_CLIENT_COUNT=2
CONFIG_BT_MAX_CONN=2

It appears the same error after building code.

best regards,

Joe

Hi Joe,

Try checking the line 23 in ble_passkey.c and line 51 in ble_latency.c in the location nrf/applications/nrf_desktop/src/modules , as shown in the snippet

There is a line BUILD_ASSERT(CONFIG_BT_MAX_CONN == 1);

Hope this helps.

Regards,

PK
