set_rate missing for rawGps

[cjffly]

Hi,

rawGps info now can be accessed with v0.38+, but I found that its missing something like "telemetry.set_rate_rawGps()" as the position can do "telemetry.set_rate_position()". Is this a missing feature or there is another way to set the rawGps access rate?

Hi, good question. You can actually just use set_rate_gps_info as the underlying mavlink message is the same.

@JonasVautherin should we add it nevertheless or add a comment to clarify this?

I first was thinking about adding it, and handling the case where somebody does set_rate_gps_info() AND set_rate_raw_gps like this:

• If both subscribe_gps_info and subscribe_raw_gps are active, use the max of both rate values
• If only one is active, take its rate

The problem is for the polling interface: what if I want to poll gps_info very fast, but subscribed to raw_gps at a slow rate? Or maybe something like:

• If both subscribe_gps_info and subscribe_raw_gps are active, use the max of both rate values
• If only one is active, take its rate
• If set_rate_ has been called (even if the subscription is inactive), use that rate in the max computation

Which then means that if you do set_rate_gps_info and then only poll raw_gps, you see the effect of the new rate (if that rate was faster than the default). Not sure if that's a problem, though... And we should document the behavior, and maybe add a log line when set_rate_ is being set to the lower value and is therefore ignored.

Not perfect, but that's the best I can think of to have a rather natural way of using both rates 😅
