TX function questions for "ble_mesh_sdk"
Feb 22, 2023 05:40
I looked at the tx function of "ble_mesh_sdk" and I have a question.
- What is the difference between light_notify() and light_slave_tx_command() functions?
- The result of my test is that I had to use the "light_notify()" function when sending data to my smartphone.
- The function "light_slave_tx_command()" had to be used when sending data to other nodes.
- Is it right to use the "light_slave_tx_command()" function to transfer data between nodes?
intlight_slave_tx_command_ll(u8 *p_cmd, intpara, u8sub_addr)
{
staticu8dbg_tx = 0;
dbg_tx++;
if(is_bridge_task_busy()){
return0; // user should retry tx command to handle this case.
}
u8cmd_op_para[16] = {0};
staticintcmd_sno = 0;
cmd_sno = clock_time() + device_address;
memset(cmd_op_para, 0, 16);
memcpy(cmd_op_para, p_cmd, 13);
cmd_op_para[0] = p_cmd[0] | 0xc0;
cmd_op_para[1] = VENDOR_ID & 0xFF;
cmd_op_para[2] = VENDOR_ID >> 8;
#if0 // for test
static u8 a_oppara[16];
memcpy(a_oppara, p_cmd, 16);
#endif
u16dst = (u16)para;
#ifSUB_ADDR_EN
if(sub_addr){
mesh_push_user_command_sub_addr(cmd_sno++, sub_addr, dst, cmd_op_para, 13);
}else
#endif
{
mesh_push_user_command(cmd_sno++, dst, cmd_op_para, 13);
}
return1;
}
intlight_slave_tx_command(u8 *p_cmd, intpara)
{
returnlight_slave_tx_command_ll(p_cmd, para, 0);
}
intlight_notify(u8 *p, u8len, u8* p_src){
interr = -1;
if(slave_link_connected && pair_login_ok){
if(len > 10){ //max length of par is 10
return -1;
}
pkt_light_notify.value[3] = p_src[0];
pkt_light_notify.value[4] = p_src[1];
u8 *p_par = &(pkt_light_notify.value[10]);
memset(p_par, 0, 10);
memcpy(p_par, p, len);
u8r = irq_disable();
if (is_add_packet_buf_ready()){
if(0 != rf_link_add_tx_packet ((u32)(&pkt_light_notify))){
err = 0;
}
}

Hi,
you are right ,light_slave_tx_command can send data to other nodes.
