Mesh serial rx

Question

Hello, 
 I have just started working with mesh and I'm using the 0.9.2 Mesh SDK. When I use the Serial interface (nrf_mesh_serial) I don't see any function about rx or rx callback. Is it true that Mesh doesn't support rx interface or I have to write it? If it supports, where can I find it? 
 Thank you very much

This is my main loop: 
 void nrf_mesh_rx_cb(const uint8_t p_data, uint32_t length) { 
	__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Rx received
"); 
}
int main(void)
{
#if defined(NRF51) && defined(NRF_MESH_STACK_DEPTH)
 stack_depth_paint_stack();
#endif


 __LOG_INIT(LOG_MSK_DEFAULT | LOG_SRC_ACCESS | LOG_SRC_SERIAL | LOG_SRC_APP, LOG_LEVEL_INFO, log_callback_rtt);
 __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- Bluetooth Mesh Serial Interface Application -----
");

 NRF_GPIO->DIRSET = 0xFFFFFFFF;
 NRF_GPIO->OUT = LEDS_MASK;

 /* Flash leds at boot */
 for (int i = 0; i < 10; ++i)
 {
 NRF_GPIO->OUT ^= BSP_LED_0_MASK;
 nrf_delay_ms(100);
 }

 mesh_core_setup();

 /* Initialize dsm and access */
 dsm_init();
 access_init();

 __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Enabling ECDH offloading...
");
 nrf_mesh_opt_t value = {.len = 4, .opt.val = 1 };
 ERROR_CHECK(nrf_mesh_opt_set(NRF_MESH_OPT_PROV_ECDH_OFFLOADING, &value));

 __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Enabling serial interface...
");
 ERROR_CHECK(nrf_mesh_serial_init(nrf_mesh_rx_cb));
 ERROR_CHECK(nrf_mesh_serial_enable());

 __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initialization complete!
");
 NRF_GPIO->OUTCLR = BSP_LED_0_MASK;
 uint32_t result;
 char hello[] = "
Hello from Nordic
";
 result = nrf_mesh_serial_tx(hello, sizeof(hello));
 __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Send result hello: %d
", result);
 while (true)
 {
 (void)nrf_mesh_process();
 }
}
 
 It worked fine. I can see the Hello text on UART (115200 bps)
If I send a application command (opcode start from 0x20) : 0x01 0x20 , I can see RX call back is triggered and text is printed out on RTT. 
 Note that you need to use the format of the packet we have, first byte is length, next is opcode and then payload. The opcode have to be inside the application opcode range I mentioned above.
