CC2640R2F: missing notify

Roberto Saini

Part Number: CC2640R2F

Hi everyone,

I'm encountering an issue concern central doesn't receive notify when the central writes on a peripheral's characteristic. The notify is sent by peripheral (seen by blepacketsniffer), but the central doesn't receive it. (See attached psd file pairing_sniff_complete.psd pkt n. 618)

If we delay the peripheral's notify of a time major than connection interval, the central receive notify (see attached psd file log_pairing.psd pkt n. 125).

Can you help me to solve this issue?

Thanks in advance.

Hi Roberto,

I'll try reproducing your issue and get back to you.

Hi Roberto,

I’m not able to reproduce the issue: I can receive a write rsp and notification in the same connection event. (Also for small connection intervals.)

Can you set a breakpoint inside else if(pMsg->method == ATT_HANDLE_VALUE_NOTI) and see if they reach the breakpoint

How are you generating the notification?

Hi Marie,

below a code snippet:

in the setParameter function

bStatus_t SimpleProfile_SetParameter( uint8 param, uint8 len, void *value ){
attHandleValueNoti_t noti;
bStatus_t status;
noti.handle = 0x1E;
noti.len = 2;
...

switch(param){
...

case SIMPLEPROFILE_CHAR6:
if ( len == SIMPLEPROFILE_CHAR6_LEN )
{
VOID memcpy( simpleProfileChar6, value, SIMPLEPROFILE_CHAR6_LEN );

noti.pValue = (uint8 *)GATT_bm_alloc( 0, ATT_HANDLE_VALUE_NOTI, GATT_MAX_MTU, &len );
if ( noti.pValue != NULL ) //if allocated
{
//place index
memcpy(noti.pValue, value, sizeof(uint8_t));
memcpy(noti.pValue+(1*sizeof(uint8_t)), value+(1*sizeof(uint8_t)), sizeof(uint8_t));
noti.pValue[0] = (uint8_t) *value;
noti.pValue[1] = (uint8_t) *(value+(1*sizeof(uint8_t)));
status = GATT_Notification( 0, &noti, 0 ); //attempt to send
if ( status != SUCCESS ) //if noti not sent
{
GATT_bm_free( (gattMsg_t *)&noti, ATT_HANDLE_VALUE_NOTI );
DebugPush("Errore nell'invio della notifica %d", status);
}
else{
DebugPush("Notifica inviata con successo");

}
}
}
else
{
ret = bleInvalidRange;
}
break;
...
}
}
The strange behaviour is that if i delay the notification, the central receive correctly it.

Hi Roberto,

Can you try sending the notification from multi_role_processCharValueChangeEvt() in multi_role.c?

Hi Roberto,

Can you please try this:

In multi_role.c, change line 858 from if to while:

 while (ICall_fetchServiceMsg(&src, &dest,

                               (void **)&pMsg) == ICALL_ERRNO_SUCCESS)

     {

       uint8_t safeToDealloc = TRUE;

       if ((src == ICALL_SERVICE_CLASS_BLE) && (dest == selfEntity))

       {
