@jp04 No I do not know the precission of the GNSS. I did not measure it.
So we need to believe the documentation. See

GNSS Performance GNSS Performance

If you can use QZSS-L1S then it says <2m 95% accuracy in Japan. Otherwise <7.8m in the city.

If I ever should do any measurements with I can post them. However sorry, there is currently no plan to do so.

Hi @jens6151-0-1-1

We have reproduced the issue, and it will be fixed in next SDK release 🙂

Thank you for your support in finding this issues so we can improve our SDK.

@CamilaSouza I have built the camera program since then, but only when enabling multi_webcam from the Kconfig file or from the OS settings, it does not work and I often get the aforementioned error.
Also If I do the following, I can enable it successfully without any problem.

. /tools/config.py examples/multiwebcam

@nimish

I see your point.
We are always trying to improve our documentation and all feedback is valuable.
I'll share your feedback with the responsible parties.

The answer is at https://forum.developer.sony.com/topic/798/wifi-add-board-connection-problem/22

@UoGTFranklin-0-1-1-1 You can define the SS pin before including the SdFat library. You can define the SS pin as a constant, for example:

const uint8_t SS = 46;

The SS pin number to the chip select pin of the SD card on the Spresence board is pin 46.

@eatbas
Although I have a different microphone (link). I experienced very low input. It was better after setting the gain to max. Can you try?

theRecorder->setMicGain(210);

Otherwise please double check the instructions
https://developer.sony.com/develop/spresense/docs/hw_docs_lte_en.html#_microphone_usage

For analog MEMS microphones the bias pins on JP10 provide power to the MEMS microphone, connect the bias pin of JP10 to the MEMS microphones power supply pin.

@NavaneethRao-2
I'm glad 🙂

@maxieaussie-0 would it be possible for you to try the recovery tool with an unmodified Spresense board?
That way we can check if the tool is working on the regular board.
Because in your case it's probably caused by the flash memory update.

@jens6151-0-1-1 Thanks for your suggestion, It worked with that program.

@CamilaSouza Thank you very much for your kind answer.
Your answers are helpful to understand.

@CamilaSouza Thanks a lot.

@gyps Thank you very much, it works !

Hi, @maxieaussie-0
I already replied in the other post, but I'll just replicate the answer here for reference.

Physically upgrading the Flash will not work because Secure CPU defined fixed size of partitions, for SPK area and User area.
So even if you re-worked SPI Flash, it is the same size on software side.

Hello, @Beckmx

Currently the code for the License Plate Recognition example is not ready to be published.
This situation might change in the future, but on the meantime I encourage you to look at the projects published on the Spresense Developer Challenge 2022
https://www.hackster.io/contests/Spresense2022

There are a lot of interesting examples to draw inspiration from 🙂
