@valeriosetti, this PR should fix suspend tests in your PR. |

Why assert here (considering asserts can be disabled), may be better to return -EADV?

Why ever use asserts if they can be disabled?

I guess the main purpose of assertion in assertion post action that is weak in Zephyr and customer is able to implement it on its own purpose. Generally, assertion is changed on hardware reset in final product as the only way for recovering device workability from unknown and unpredictable situation.

Is this the real place where device requires hardware reset in "fields"?
It seems @omkar3141 suggestion is more suitable. Since functional prototype returns operation status, it is better to return error code.

This 'ensure' works only when asserts are enabled, otherwise this can cause locking, better to return error code to let higher layer handle it.

I'd suggest to add an input parameter to this macro (either bt_mesh or bt_mesh.flags). Without it you get the impression that this macro evaluates to a build-time constant, which is not true.
Instead of checking the `enabled` flag, check if BT_MESH_SUSPENDED is set in the legacy advertiser thread. BT_MESH_SUSPENDED is set earlier than advertiser is stopped and will prevent the advertiser send anything earlier. Signed-off-by: Pavel Vasilyev <[email protected]>
k_sleep may not be enough to let advertiser send the message. Instead we should rely on the bt_mesh_send_cb. Signed-off-by: Pavel Vasilyev <[email protected]>

k_sleepwith semaphore before suspending mesh as k_sleep may not be enough to let advertiser send the message. Instead we should rely on the bt_mesh_send_cb.This PR fixes mesh suspend tests in #79931
