Not receiving Enquire link PDU from provider in my onPDU handler.

[bluewithanas]

To ensure no connection resets between my application & provider , my provider has adivsed application to respond with enquire_link resps in reply to their Enquire_links.

I am already forwarding Enquire_link from application to provider. Now they are asking us to implemeting vice-versa.

But, i am not receving their enquire_link. They forwarded us their Pcap file & I checked, indeed they do forward us.

this is my SMPP setting

`

session, err := gosmpp.NewSession(
	gosmpp.TRXConnector(tLSDialer, creds),
	gosmpp.Settings{
		EnquireLink: 3 * time.Minute,

		ReadTimeout: 4 * time.Minute,

		OnSubmitError: func(_ pdu.PDU, err error) {
			log.Println("SubmitPDU error:", err)
			g.HandleConnectorEvents(err, 0, OnSubmitError)
		},

		OnReceivingError: func(err error) {
			log.Println("Receiving PDU/Network error:", err)
			g.HandleConnectorEvents(err, 0, OnReceivingError)
		},

		OnRebindingError: func(err error) {
			log.Println("Rebinding but error:", err)
			g.HandleConnectorEvents(err, 0, OnRebindingError)
		},
		OnPDU: g.HandlePDU(),
		OnClosed: func(state gosmpp.State) {
			log.Println(state, " State: ", state.String())
			g.HandleConnectorEvents(nil, state, OnClosed)
		},
		OnRebind: func() {
			log.Println("OnRebind callback invoked!!")
			g.HandleConnectorEvents(nil, 0, OnRebind)
		},
	}, 10*time.Second)
if err != nil {
	return nil, errors.Wrap(err, "go smpp new session ")
}

`

can it be due to i am using onPdu instead of onAllPDU ?

I have logged every PDU, but i do not see enquire link PDU.
