How to receive notification in multi2.1 project?

katuxa

Hi all.

I use multi 2.1 project. When connection is done with slave, slave starts to send notification with 1000ms interval .

I used folow code for receiving notification in old multi(2.0) project:

static void SimpleBLEMulti_processGATTMsg(gattMsgEvent_t *pMsg)
{
if ((gapRoleNumLinks(GAPROLE_ACTIVE_LINKS) > 0))
{

if (pMsg->method == ATT_HANDLE_VALUE_NOTI ||
pMsg->method == ATT_HANDLE_VALUE_IND)
{
attHandleValueNoti_t noti;

noti.handle = pMsg->msg.handleValueNoti.handle;
noti.len = pMsg->msg.handleValueNoti.len;
noti.pValue = pMsg->msg.handleValueNoti.pValue;

TLwrite(noti.pValue, noti.len);

.........

in multi 2.1 it doesn't work. In debugging I see that Process GATT messages and events not happen.

I see notification messages in packet sniffer.

How to receive notification messages in multi(stack 2.1) ?

Thanks

I checked that receive notification works in central project (stack 2.1). It doesn't work only in multi 2.1. It is bug?

There was a bug fixed recently in the multiRole project. It sounds like this may have been part of it. I would recommend using the new patch.

Hello. Can you attach a sniffer capture of what you are attempting to do?

Have you modified other parts of the multiRole project? The multiRole device should be exchanging MTU length and performing characteristic discovery after establishing a connection. I don't see any of this in your capture.

In any case, I have modified the problem on the default multiRole and am currently debugging it.

multi.psd with exchanging MTU, but it isn't solves the problem.

Hi Tim,

I test latest multi-role patch and re-produce this problem. I enter debug mode to make sure the program go to GATT_ExchangeMTU(), but there is no response. I think central doesn't send GATT_ExchangeMTU() command

Hi Tim,

Sorry, I use frontline to catch packet. I see the ATT_Exchange_MTU request and response, but program doesn't trigger ATT_MTU_UPDATED_EVENT.

Hi,

Please add

/*-----------------CLIENT------------------*/

// Initialize GATT Client

VOID GATT_InitClient();

// Register to receive incoming ATT Indications/Notifications

GATT_RegisterForInd(selfEntity);

// Register for GATT local events and ATT Responses pending for transmission

GATT_RegisterForMsgs(selfEntity);

Hi YUHUA Hu, thank you so much!!!

Yep thank you!! I should have seen this as it is documented in the software developer's guide (Section 5.3.3.1 Using the GATT Layer Directly).

Anyway, I'll add it to the multiRole project since it does use the simpleGATTprofile which includes a notifiable characteristic
