Telemetry compilation fails

[iluetkeb]

When I enable the telemetry app, compilation fails with the following error:

Hi Ingo,

Maybe it's a problem of configuration, please use the telemetry config profile to make sure that you're using the right config.

If you're using the docker container you should type the next command to configure it:

• make distclean
• ./tools/configure.sh olimex-stm32-e407/telemetry

Thanks.

Ah, I've been trying to compile for simulation.

I think you're meant to use "depends" statements in the config for your app to declare requirements on particular devices. This will then disable the option to compile your app if the device is not also selected.

Hi, I think that in the simulator you can't use drivers that use peripheral, so I recommend you to use a board, because the simulator have very little functionality. Thank you for the suggestion, the app is still in a early stage of development.

Old, we have changed the app. Closing
