Hi Brent,

Have you already created a new case? If so, what is the case ID of the new case?

Kind Regards,

Bjørn

Hi, Bjørn

I closed this case by mistake, not sure whether you can still see it , have to raise the mentioned problem as another case.

Hi, Bjørn

Thanks for your help, finally I find the reason.

There is ACCESS_MODEL_COUNT in "nrf_mesh_config_app" . It is actually controlls the memory use on model add.

After Adjust the model qty, there is no problem anymore.

---------------------------------------------------------------------------------------------------------

Here I met another problem, please help.

I am using proxy.c to establish an data link with smartphone via mesh_GATT.

What I am doing is like this:

For TX ,

it is actually a service notification

1. I created a function to use proxy_connection, I understand, only one connection permited.

static void send_data_to_smartphone(proxy_connection_t * p_connection)
{

__LOG(LOG_SRC_BEARER, LOG_LEVEL_INFO, "START TX\n");

proxy_enable();
if (packet_alloc(p_connection, MESH_GATT_PDU_TYPE_NETWORK_PDU, SEAT_BELT_PACKET_SIZE, NRF_MESH_SERVICE_BORDER_TOKEN) ==
NRF_SUCCESS)

{
memcpy(p_connection->p_alloc_packet, seat_belt_data.tx_data, sizeof(seat_belt_data.tx_data));
// memset(seat_belt_data.tx_data,0xFF,SEAT_BELT_PACKET_SIZE);
}

packet_send(p_connection);

}

2. I called this function in

" static void gatt_evt_handler(const mesh_gatt_evt_t * p_evt, void * p_context)"

at position:

case MESH_GATT_EVT_TYPE_TX_READY:
__LOG(LOG_SRC_BEARER, LOG_LEVEL_INFO, "TX ready\n");

send_data_to_smartphone(p_connection);
beacon_cycle_send(p_connection);
break;

3. Smartphone side: start nRF Connect

Result: 1) from smartphone I can see data keep coming ,but it is not my data;

2) in debug process,
__LOG(LOG_SRC_BEARER, LOG_LEVEL_INFO, "START TX\n");

do not show up?

for RX

I follow rx_handle function ,

case MESH_GATT_EVT_TYPE_RX:
__LOG(LOG_SRC_BEARER, LOG_LEVEL_INFO, "RX\n");
rx_handle(p_connection,
p_evt->params.rx.pdu_type,
p_evt->params.rx.p_data,
p_evt->params.rx.length);

to file "network .c", inside

uint32_t network_packet_in(const uint8_t * p_packet, uint32_t net_packet_len, const nrf_mesh_rx_metadata_t * p_rx_metadata)

I put :

#if GATT_PROXY
if(p_rx_metadata->source==NRF_MESH_RX_SOURCE_GATT)
{
__LOG(LOG_SRC_BEARER, LOG_LEVEL_INFO, "RX2_Start\n");
memcpy(seat_belt_data.rx_data,&net_decrypted_packet,sizeof(net_decrypted_packet));
}

try to memcopy the pocket arrive from mesh GATT.

Result.

1. smartphone side: when I try to write data, the connection terminated immediately,.

2. in debug process, I can not see any reaction , even log info.

Please help how to move at this point.

Thanks a lot.

Brent

Hi Brent,

Error 4 refers to NRF_ERROR_NO_MEM (see nrf_error.h). You should also take a look at line 333 in main.c to see by which function the error is called.

You can also look where 0x000267B9 in the map file which can be located in the build folder here: nrf5_SDK_for_Mesh_v2.1.1_src\examples\light_switch\proxy_client\build\light_switch_proxy_client_nrf52832_xxAA_s132_6.0.0_Debug\. Open up the .map file extension & look for where the 0x000267B9 is located.

Did you remember to initialize the model to allocate, initialize & bind the model to the element like described in the documentation. I can see that you call the light_lightness_client_init() function. Would you mind uploading the light_lightness_client_init() function code? Did you call access_model_add() like in the config_server_init() function in config_server.c of the light switch proxy client example?

Also, did you define the opcode handlers like described in the documentation? If I were you, I would take a look at how the configuration server, health server or simple on off server is initialized & do something similar for the other two models you want to add.

Kind Regards,

Bjørn

Hi, Bjørn

I upgraded mesh sdk to 2.1.1, and followed to documentation for add new models, you can see the steps in message.

Thanks

Hi Brent,

Which mesh sdk version are you currently using? Have you already taken look at the documentation provided here?

Kind Regards,

Bjørn
