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, 

However, I was not able to build an image with iperf ( egion `FLASH' overflowed by 868 bytes)

How do you build the Modem Shell sample? How do you modify the sample?

In the Modem Shell sample, it already enables Iperf3 by CONFIG_MOSH_IPERF3=y.

Hi ,

I've modified prj.conf

CONFIG_MOSH_IPERF3=y

CONFIG_MOSH_SOCK=n

CONFIG_MOSH_PING=n

CONFIG_MOSH_CURL=n

CONFIG_MOSH_LINK=y

CONFIG_MOSH_SMS=n

CONFIG_MOSH_GNSS=n

CONFIG_MOSH_LOCATION=n

and build failed with error

region `FLASH' overflowed by 868 bytes

Any special reason to disable them?

Without modification, it will not cause the overflow.

I intended to create a smaller image. Looks like I still have to learn a lot. I've prepared a clean build with following configuration

CONFIG_MOSH_IPERF3=y

CONFIG_MOSH_SOCK=y

CONFIG_MOSH_PING=y

CONFIG_MOSH_CURL=n

CONFIG_MOSH_LINK=y

CONFIG_MOSH_SMS=y

CONFIG_MOSH_GNSS=n

CONFIG_MOSH_LOCATION=n

however iperf command is not visible

You could try to build with overlay-non-offloading.conf.
