Implementation of repeaters
We look at the basic implementation of a repeater.
Module definition, include
#define ToCoNet_USE_MOD_NWK_LAYERTREE
#define ToCoNet_USE_MOD_NBSCAN
#define ToCoNet_USE_MOD_NBSCAN_SLAVE
#define ToCoNet_USE_MOD_NWK_MESSAGE_POOL
#define ToCoNet_USE_MOD_DUPCHK
// includes
#include "ToCoNet.h"
#include "ToCoNet_mod_prototype.h"
cbAppColdStart()
The application ID and channel are determined here. The initialization process is described in the vProcessEvCore()
function.
void cbAppColdStart(bool_t bAfterAhiInit) {
if (!bAfterAhiInit) { // before AHI init, very first of code.
// Register modules
ToCoNet_REG_MOD_ALL();
} else {
// TWELITE NET configuration
sToCoNet_AppContext.u32AppId = 0x12345678;
sToCoNet_AppContext.u8Channel = 18;
sToCoNet_AppContext.bRxOnIdle = TRUE;
// Register user PRSEV.
ToCoNet_Event_Register_State_Machine(vProcessEvCore);
}
}
cbToCoNet_vNwkEvent()
The relay processes the E_EVENT_TOCONET_NWK_START E_EVENT_TOCONET_NWK_DISCONNECT
message.
void cbToCoNet_vNwkEvent(teEvent eEvent, uint32 u32arg) {
switch (eEvent) {
case E_EVENT_TOCONET_NWK_START:
A_PRINTF( LB"[E_EVENT_TOCONET_NWK_START]");
break;
case E_EVENT_TOCONET_NWK_DISCONNECT:
A_PRINTF( LB"[E_EVENT_TOCONET_NWK_DISCONNECT]");
break;
}
}
cbToCoNet_vRxEvent()
The method of reception is much the same as for simple nets, with the exception of the tsRxDataApp
structure.
void cbToCoNet_vRxEvent(tsRxDataApp *pRx) {
uint8 *p = pRx->auData;
// Show packets
if (pRx->u8Cmd == TOCONET_PACKET_CMD_APP_DATA) {
// Basic information
uint8 u8lqi_1st = pRx->u8Lqi; // LQI
uint32 u32addr_1st = pRx->u32SrcAddr; // Sender
// Interpreting the data
uint8 u8b = G_OCTET();
...
}
}
vProcessEvCore()
On system start-up E_EVENT_START_UP
of the data, set the tsToCoNet_NwkLyTr_Config
structure, execute the ToCoNet_NwkLyTr_psConfig()
function, initialize the network with the ToCoNet_Nwk_bInit()
function and start the network with the ToCoNet_Nwk_bStart()
function.
The setting must specify the repeater (TOCONET_NWK_ROLE_ROUTER
), the number of layers, and the NB beacon (TOCONET_MOD_LAYERTREE_STARTOPT_NB_BEACON
).
We get E_EVENT_TOCONET_NWK_START
event after network start. It also receives E_EVENT_TOCONET_NWK_DISCONNECT
if the upper node is lost.
static tsToCoNet_NwkLyTr_Config sNwkLayerTreeConfig;
static tsToCoNet_Nwk_Context* pContextNwk;
static void vProcessEvCore(tsEvent *pEv, teEvent eEvent, uint32 u32evarg) {
switch (pEv->eState) {
case E_STATE_IDLE:
if (eEvent == E_EVENT_START_UP) {
memset(&sNwkLayerTreeConfig, 0, sizeof(sNwkLayerTreeConfig));
// Determination of the number of layers
sNwkLayerTreeConfig.u8Layer = 4;
// Use of NB beacon-based networks
sNwkLayerTreeConfig.u8StartOpt =
TOCONET_MOD_LAYERTREE_STARTOPT_NB_BEACON;
// Starts as a repeater
sNwkLayerTreeConfig.u8Role = TOCONET_NWK_ROLE_ROUTER;
pContextNwk = ToCoNet_NwkLyTr_psConfig(&sNwkLayerTreeConfig);
if (pContextNwk) {
ToCoNet_Nwk_bInit(pContextNwk);
ToCoNet_Nwk_bStart(pContextNwk);
} else {
// fatal error
}
}
break;
default:
break;
}
}
