SUPL and IP protocol

[Tron]

How is it with SUPL and NB-IoT, will it work? AFAICS, in the example code, the supl_support code only uses TCP, and this is not a protocol supported when the device is using NB-IoT. Is it possible to get SUPL to work over UDP, and if that is the case, how to set up the connection to the SUPL-server?

Yours,

Hi Tron,

This depends on the network your device is connected to, but generally no, TCP and NB-IoT do not work great together.

(Most networks do not block TCP on NB-IoT by default, but can drop TCP packets when there is too much strain on the network traffic. e.g. I tested the GPS with SUPL sample on the NB-IoT network and it worked).

I will need to do some investigations with regards to your last questions.

BR,

This needs to be added as a new feature or a workaround.
It has been reported internally.
It is also discussed in this thread with some additional information as well: https://devzone.nordicsemi.com/f/nordic-q-a/63085/a-gps-download-fails-mid-session
