binc_agentmanager_register_agent succeeds on first, but fails on second and third adapter

[abqjln]

Trying to set up multiple clients on the Pi3/bluez 5.66. Same issue on Pi4/bluez 5.78. Both using the internal and two USB adapters. The adapters get configured properly but binc_agentmanager_register_agent fails at binc_agentmanager_call_method twice.

The input adapter and agent path are unique (borrowing your random_string function from the application config previously), yet the error show it thinks the second attempt (with unique adapter and path) is a duplicate, and then fails at the default agent manager because it is null. I don't understand what the manager is doing??

Also noted there's no way to trap this type of error--can it be done? Thank you.

Modified code from agent.c
Agent *binc_agent_create(Adapter *adapter, const char *path, IoCapability io_capability) { Agent *agent = g_new0(Agent, 1); agent->path = g_strdup(path); agent->connection = binc_adapter_get_dbus_connection(adapter); agent->adapter = adapter; agent->io_capability = io_capability; bluez_register_agent(agent); log_error( TAG, "[%s]: bluez registered ok using adapter %s", __func__ , binc_adapter_get_path( adapter )); // *******MY LINE binc_agentmanager_register_agent(agent); <<<<<<<<<<<<<<---FAILS HERE log_error( TAG, "[%s]: manager_registered", __func__ ); return agent; }

produces the following with hc0, hc1, hc2 initialized
