Softdevice: Not responding to MCUMGR bootloader_info command

[JordanYates]

I am attempting to use the nRF Connect for Mobile application to test the MCUmgr implementation on my device running the Softdevice.
I am able to successfully run the "OS/Echo" and "OS/mcumgr_params" commands, but "OS/bootloader_info" never gets through.

As unlikely as it seems, this appears to be an issue at the Softdevice controller level based on the Wireshark traces I have collected.

The central device is repeatedly sending the command, with no acknowledgement from the Softdevice.
mcumgr_bootloader_info.pcapng

Version information:

 * NCS v2.7.0
 * nRF Connect for Mobile v4.28.1
 * Android 13

Reproduction application:

west build -b nrf52840dk/nrf52840 zephyr/samples/subsys/mgmt/mcumgr/smp_svr/ -- -DOVERLAY_CONFIG="overlay-bt.conf" -DCONFIG_BT_AUTO_PHY_UPDATE=n -DCONFIG_MCUMGR_GRP_OS_BOOTLOADER_INFO=y

(Update)

My colleague can get the same menu in the app on his pixel 4a. 

He ran the "OS/bootloader_info" command and got the result as the following figure. Also updating via DFU works as expected without issue. 

What is your destination? If you just want to update via DFU, this command is not necessary and will not impact the DFU.

What is the phone you use? I use Pixel 6a with Android 14, but cannot find the same menu in the app as you.

Could you try to use the nRF Device app?
