Only one message recieved when multiple messages are sent. about node-smpp HOT 5 OPEN

Without any code it's hard to guess but I would start checking the vendor side. This might be something on their side.

If you aren't receiving the messages as well, keep in mind that some brokers put some limits to avoid spam.

If this isn't your case where all sent messages were received and you didn't receive the DLRs, you need to check with them.

@guicuton Thanks for the prompt response 🙇

smpp.on("deliver_sm", async (pdu: any) => {
  const message: string = pdu.short_message.message
  const sourceAddress: string = pdu.source_addr
  const destinationAddress: string = pdu.destination_add

  const responsePdu = pdu.response()
  smpp.send(responsePdu)

// rest of the logic

That is what my code looks like. When multiple message are sent to my server at the same time only one is being caught in the deliver_sm callback sometimes both are being caught not sure why this happens. Do you see anything wrong with the code?

Use event submit_sm to get received message

session.on("submit_sm", async (pdu) => { const message = pdu.short_message.message; const sourceAddress = pdu.source_addr; const destinationAddress = pdu.destination_addr; });
