no, I didn't solve it right now...please refer to this link you get some direction..https://github.com/stby4/nrf_mesh_throughput

Hi pat24,

I encounter the same issue. Did you solve it?

Sorry about the delayed response.

If you want to publish an acknowledged message, you should use access_model_reliable_publish().

Payloads greater than NRF_MESH_UNSEG_PAYLOAD_SIZE_MAX will be segmented.

Note that you must retain the data provided in access_message_tx_t::p_buffer until the acknowledged transfer has ended (see access_reliable_t::status_cb) or the message is cancelled by access_model_reliable_cancel.

Br,
Joakim

thanks for responding
I have a limited number of devices so I compromise with throughput .I successfully transfer and receive 49 bytes from client to server but I want to send more. if the message is segmented then we can send up to 380bytes is it correct .?so how to achieve to send more than 49 bytes of data from ble mesh. is it necessary to call access_model_reliable_publish().for segmented messages.

Hi.

Please note that Bluetooth Mesh is best suited for use cases where you have multiple nodes, possibly over a large area, but where the required data throughput is low.

Are you locked to using Mesh for the large data transfer? Or are you open for other solutions or suggestions?

Anyways, if you want to publish an acknowledged message, you need to call access_model_reliable_publish().

Br,
Joakim
