Re: [Paparazzi-devel] telemetry stream redirection?

[Gautier Hattenberger]

Hello Chris,

An option for that is to create a kind of virtual device that implement
the structure 'link_device':
https://github.com/paparazzi/pprzlink/blob/master/tools/generator/C/include_v2.0/pprzlink_device.h

This device can act as a buffer to store the data (implement 'put_byte'
and 'put_buffer' for that purpose) and only load when the 'send_message'
is called.

You can check the UDP driver, which is working with this principle:
