      This is the direct link
      https://github.com/ds-dyad/10n2-app/blob/master/sdk.config

      This is not my project, so I cannot give details.

      I do not know if the speed plays an important role here. I added it to my code. (I interface LSM303)

      Wire.setClock(400000); // 400KHz

      On the first glance the code looks good.

      I would try out one of the Arduino libraries like this https://github.com/adafruit/Adafruit_MPU6050. Just the given example to check if the hardware connections are good before writing own code.

      @gyps
      Also try to increase the upload speed.
      There is a configuration ${config:spresense.serial.port}. I have no clue how to set it.
      The alternative is hack it into the file spresense-sdk/spresense/sdk/tools/flash.sh

      UART_BAUDRATE="230400"

      Higher speeds are not successful.

      Also do not forget the clean "make clean -j".

      @CamilaSouza
      Hi Camila, I still hope to get an answer for the previous question.

      The mics are connected on the mic pins of the extension board (followed the instruction here: https://developer.sony.com/develop/spresense/tutorials-sample-projects/spresense-tutorials/using-multiple-microphone-inputs-with-spresense)

      The earphone is connected to the headphone connector on the extension board (for audio output).

      Since this project is for SNR measurement, I use the audio recorder mode. My question is: Can I generate an audio beep to earphone through headphone connector as an alarm? I do not know how to combine the audio recorder mode and the audio player mode together.

      Thank you in advance for any help,

      Best,

      Larry

      @dshilov-1-1 Thank you for your reply.
      I only have the extension board. I thought that was a different sensing add-on as the accelerometer included in the EVK-701 is not BMI160.

      I do have another IMU which I tried to use but I keep getting the failed to connect to I2c error. is there a way to check if the hardware is fine or not?
      Many thanks!

      Hi, @jens6151-0-1-1

      Thank you for your feedback!
      I'll share your feedback internally and investigate if there is a reason why it is done this way.

      @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.

      @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.

      @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.
