Hi all,
On my system (Raspberry PI 3), the RX path doesn't work anymore
following a restart of the bluetooth-meshd daemon. I have tracked down
that to the fact that the receive callbacks are setup before the HCI is
fully initialized. Said otherwise, BT_HCI_CMD_LE_SET_SCAN_PARAMETERS is
called before BT_HCI_CMD_RESET and the callback calling
BT_HCI_CMD_LE_SET_SCAN_ENABLE is not called. This timing dependent and
probably not reproducible on all hardware.
I have workarounded the issue by adding a small delay between the HCI
initialization and the call to node_attach_io_all():
diff --git a/mesh/mesh.c b/mesh/mesh.c
index 9b2b2073b..1c06060f9 100644
--- a/mesh/mesh.c
+++ b/mesh/mesh.c
@@ -167,6 +167,10 @@ bool mesh_init(const char *config_dir, enum mesh_io_type type, void *opts)
mesh_io_get_caps(mesh.io, &caps);
mesh.max_filters = caps.max_num_filters;
+ for (int i = 0 ; i < 100 ; i++) {
+ l_main_iterate(10);
+ }
+
node_attach_io_all(mesh.io);
return true;
I guess there is a better way to do that by waiting for the HCI to be
fully initialized before calling node_attach_io_all() or by using a
callback instead. However I do not know the codebase good enough to fix
that properly.
