Inquiry on Setting Up Interrupt for UDP Reception on nRF9160

[toshi_j]

I am currently working on a project using the nRF9160 DK and I am implementing CoAP communication. In my application, I would like to trigger an interrupt on the firmware side whenever the modem receives a UDP packet, in order to call function for processing the received data.

I understand that using the LTE link control (lte_lc) library, I can handle events such as changes in the RRC connection mode. However, for optimal implementation, I am specifically interested in setting up an interrupt or event that directly corresponds to the reception of a UDP packet by the modem.

Could you please provide guidance on whether it is possible to configure such an interrupt for UDP packet reception? If it is not directly supported, are there any recommended alternative approaches to achieve this functionality?

An interrupt is a pretty high prio resource. I would not use it for something like a incoming message.

For network communication it's more common to use functions as "poll" (see the sample for poll ).

Thank you for your response. I appreciate the guidance provided. I will consider using polling to handle UDP packet reception. Your advice has been very helpfull !
