@m-Lewis The easiest way to check that the date and time are valid is:
/* Check update. */
if (Gnss.waitUpdate(-1))
{
/* Get NaviData. */
SpNavData NavData;
Gnss.getNavData(&NavData);
/* Check date and time. */
if (NavData.time.year > 1980)
{
/* Date and time are valid */
}

@m-Lewis The code that I sent you records in mp3 format for 10 seconds and then ends. That's why you don't get logs after that.
I noticed that WAV recording and GNSS usage doesn't work on SDK 2.0 together. There is a bug. I'll try to investigate it.
I have two solutions for now:
Below is the code for the second solution:
// GNSS and Audio at the same time example, while writing data to a logfile and output to Serial port
// M. Lewis
bool doAudio = true; // Record Audio
bool doGnss = true; // GNSS/GPS

}

To my knowledge there is no such method to set the radio directly. The only way to set it directly, that I know of, is via the presetBroadcastStation and then use setPlayContent to go to that preset as you have described.
In the documentation I can't see any other valid "uri" than contnetId=X for radio, so it don't looks like you have something like "uri":radio:fm?frequency?XXXX unfortunatly.
Hi @pnj
It would help a lot if you could provide the code/sketch you are trying to build.
Also, what sensor are you using? What libraries?

I tried the following code just to see if using the rewind macro would generate any error and it didn't:
Using SDK 2.0.2
void setup() {
// put your setup code here, to run once:
/* This code is just to test the build for errors. */
FILE *fp = NULL;
rewind(fp);
}
void loop() {
// put your main code here, to run repeatedly:
}

@pnj said in Auduino Compiling error : stdio.h:
some example
Yes, it is the same hard upper limit (55) for al devices, but some devices like HT-ZF9 the hardware limitation can be lower (50 in this case) but you can never get above 55 for any device.
Hi @grolschie, just got a reply from the engineers and the max volume in the API is a safety feature, so you don't destroy your speakers by accident. The reason you don't have this limitation on the IR remote is that you do it incrementally and there for probably notice then it gets to loud. But since you can set the volume directly via the API a max cap is required.
One case what was mentioned is if you are using google assistant and say "Hey google, set STR volume ten" this will set max volume.
@grolschie I currently don't have access to any of the STR-XXX devices so I can't test, the intended usage is to query the device for the current volume and get the max and min volume, (I would scale the value so it is always between 0-100 from my device handler) in theory min and max volume this can be different for every device (don't think it is), but for example the device I have HT-Z9F and SRS-ZR5 have min 0 and max 50, and the same is then using the IR remote.
What happens then you set the volume to 55 with setAudioVolume, will it be 74 of 55 on the device?
