CCS/CC2640R2F: Multi_Role stops advertising after connecting and disconnecting once.

I tried with SDK version 1.50.00.58 using BLE4.2 also but getting the same issue in this multi_role example.

Thank You

I am having the exact problem while using multi_role sdk1.50.0.58 example as peripheral to multi masters (android smartphones).

To specify I think it appears when all the connection slots are being used (at the same time, concurrently that "can't adv, no links" appears) and then some of them released.

Fresh and clean multi_role example uses MAX_NUM_BLE_CONNS=1 in compiler predefined symbols, so when one device connects and then disconnects cc2640 doesn't advertise anymore. In my scenario I use MAX_NUM_BLE_CONNS=3, so when I connect one device and disconnect it advertises as it should be. When I connect two devices and disconnect one of them it still can discover cc2640. But when I connect three devices to cc2640 and then disconnect one or more it doesn't advertise! And of course it's impossible to connect to it afterwards without a reset.

I used a workaround to force cc2640 to advertise which I DO NOT recommend because in my case it led to some issues with bonding and uncontrolled disconnecting. In multi.c in definition of 

gapRole_processGapMsg (...) {
...
switch(pMsg->opcode){
...
case GAP_LINK_TERMINATED_EVENT:
...
  if (!gapRole_AdvEnabled)
      {
        gapAdvertisingParams_t params;
        Util_restartClock(&startAdvClock, gapRole_AdvertOffTime);
        params.eventType = gapRole_AdvEventType;
        params.initiatorAddrType = gapRole_AdvDirectType;
        VOID memcpy(params.initiatorAddr, gapRole_AdvDirectAddr, B_ADDR_LEN);
        params.channelMap = gapRole_AdvChanMap;
        params.filterPolicy = gapRole_AdvFilterPolicy;
        GAP_MakeDiscoverable(selfEntity, &params);
      }
}
break;
...
}

Please Ti, can you look into it and propose a solution?

Actually I am using a custom board in which there is no any button. So I can't use any button functionality. I was not able see any menu and button option also because in my board there is no any display interfaced,     and uart pins are connected with gps. So I couldn't verify that. Thanks for verifying. I think I have to change in code for readvertise if  advertising is not happening. Now my question is I have to use the scanning and advertising both. So let's say on power up board is advertising and after 1 min board need to scan the available peripheral devices. And this will happen continuously means device will advertise and then scan periodically. So can you suggest how should I do this.  In what part of multi role I need to change. Thank you.

Thank you for hint,

I have added following lines to multi.c and so far it looks like working (for 1 connection as well as 2 simultaneous):

gapRole_processGAPMsg(gapEventHdr_t *pMsg){
...
switch (pMsg->opcode)
...
case GAP_LINK_TERMINATED_EVENT:
...
if (!gapRole_AdvNonConnEnabled) //added
{

uint8_t adv = TRUE; //added
GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &adv, NULL); //added

} //added
