[v1,PTS] Included peripheral mode for fixing of few PTS Test Cases

Commit Message

Prathibha Madugonde June 20, 2024, 11:22 a.m. UTC

From: Prathibha Madugonde <[e-mail]>

Fix for below Test Cases:
GAP/SEC/SEM/BV-56-C
GAP/SEC/SEM/BV-57-C
GAP/SEC/SEM/BV-58-C
GAP/SEC/SEM/BV-59-C
GAP/SEC/SEM/BV-60-C
GAP/SEC/SEM/BV-61-C

For all above test cases, PTS tool is adding Battery Level Characteristics in the GAP service. And PTS is expecting to write value to Battery Level Characteristics.
When IUT and PTS are connected from bluetoothctl tool, GAP service and its characterisitics are not showing in the bluetoothctl terminal.
Therefore need to use other existing tools, here we used btgatt-client tool.
For GAP/SEC/SEM/BV-56-C , GAP/SEC/SEM/BV-57-C, GAP/SEC/SEM/BV-58-C test cases the IUT should be in peripheral mode(advertise and accept connection) and GATT client role as per GAP.TS.p44.
Added peripheral mode in the btgatt-client tool for PASSING those test cases.

Ok, this is sort of weird if that is intentional to expose Battery
Level Characteristic on GAP service, so there is no Battery Service?
Not sure why it would be using Battery Level either, or is this
something you can influence with some (PIXIT?) configuration? If the
idea is just to have the peripheral acting as a GATT client any
attribute would do it so the choice here seems really odd, what I'd
expect is that one could configure the attribute/handle that it wants
to send the GATT operations.
