I am trying to make a bluetooth mesh zephyr node with 2 elements. After provisioning (which assigns 2 node adresses) meshctl ask for the composition data. This fails with Not enough tailroom for TransMIC:
[bt] [DBG] dev_comp_data_get: (0x20001950) net_idx 0x0000 app_idx 0xfffe src 0x0 [bt] [ERR] bt_mesh_model_send: Not enough tailroom for TransMIC
What configuration option do I need to change (I am working on nrf51822) ?
