How to measure DL/UL throughput with Thingy:91 ( no debbuger )

[finch]

I would like to measure some basic parameters using Thingy:91.  Modem shell (MoSh) provides all the necessary tools. However, I was not able to build an image with iperf ( egion `FLASH' overflowed by 868 bytes) . Do I understand correctly that there is no other way to create such image when developing using USB flash ?

Hi, 

Could you try to build this modem_shell.7z sample with overlay-iperf3.conf?
The west command:

west build -p -b thingy91_nrf9160_ns -d build_thingy91_nrf9160_ns -- -DOVERLAY_CONFIG=overlay-iperf3.conf

Thanks . Now it works. It looks like I need to study more toolchains.
