Undefined function nrf_mesh_unique_token_get() in nRF5_SDK_for_Mesh

[Armin]

I added the Generic OnOff Model from the thingy52-mesh-provisioning-demo to the Light Switch Proxy Client example from the nRF5_SDK_for_Mesh and get a linker error for the function nrf_mesh_unique_token_get() as follows:

build/light_switch_proxy_client_nrf52840_xxAA_s140_6.0.0_Debug/obj/generic_on_off_client.o: In function `send_reliable_message':

undefined reference to `nrf_mesh_unique_token_get'

Question: where is the function nrf_mesh_unique_token_get() defined?

Hi Armin, 

 

The access_token is something we are implementing in SDK v2.0.3, it can be removed for now. Please just simply comment out the  reliable.message.access_token = nrf_mesh_unique_token_get(); in send_reliable_message in genedic_on_off_client.c

 

Please be aware that what implemented in the repo was just a demo application, it's not the proper implementation of the generic on off model.

Sorry if bother, but can you explain help me the function of access_token for doing? I read the explanation in the code but I do not understand.
 / ** Token that can be used as a reference in the TX complete callback. * /
    nrf_mesh_tx_token_t access_token;

Hi Hai, 

The access_token used as an ID of your message, so when you have the TX_COMPLETE event , you can find the token comes with the event and know which exact message has been sent
