@CamilaSouza Thanks a lot for the inputs. I had not seen the test scripts. It worked for me.

@jens6151-0-1-1 Hi Jens. Ouch! Thanks for clarifying this. I was hoping to store my tflite model which is not so lite :-)-tried all conversion options with no luck . Converted to const it ended up around 56,172,546 🙂 I think I might have to change to a Renesas RZ/V2L MCUs! (I am not into Coral Boards and alikes). I was only using Arduino for a quick check but yes even with any other option there is no way the model would fit!

Thanks
P.S
I have not tried this process with the original memory chip

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

@CamilaSouza Hi. Thanks for keep helping me with this topic. Yes, I contacted the GS2200M module manufacturer (Telit) and they asked me to contact the supplier (IDY) instead.

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

@CamilaSouza Thanks a lot.

Hey, @Jolle
What is your windows version?

@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 🙂

@gyps

Thank you for the feedback!

Hi @jp04,

I had the same situation here. 3-4 satellites are not enough to get a fix. I got a fix quickly when the readings showed 7-10 satellites.

I recommend to try the following.

You might have bad luck with the sight of the satellites. Therefore try again at another location or another time. Attach a battery and go outside or at least near a window. You can use an augmented reality app on your phone that shows where the satellites are. Add other satellites than the default. For example set satType to eSatGpsQz1cQz1S if you are in Japan. See the comments in the demo. Try to attach an external GPS antenna. It requires additional parts (available at Adafruit or Akizukidenshi) and requires soldering. I can give you some advice if you want. Check if the wifi board or anything you place around the antenna causes interference.

Should you get a fix, you can save the satellite data for a hot start the next time. This call persists the data to flash memory in case you power off. Don't use the function on each update as it will wear off the flash memory.

Gnss.saveEphemeris();

Btw. I would be interested your opinion on the wifi addon board you ask for in another post. Will you send large data like images? Is it fast and reliable?
I flashed the AT firmware to one of my ESP-32 boards and connected it via UART. It works but the transfer rate is pretty slow due to the limitting UART.

@Noor and @jp04

You two are using two different WiFi board options, but you are dealing with the same issue of how to upload the certificates related to SSL connections by using AT command.

I thought you might benefit from getting in touch.

Hey, @Ajit01

In the past when I got random results from analog signals I had forgotten to connect the sensor GND with Spresense GND. Please check this.

But to make sure that everything is good with the spresense analog in, you can test connecting the 3.3V pin to A0 and then the 5V pin to A0 and printing the value.

Doing this here I got 658 with 3.3V and 986 with 5V.

Code I used to test mine:

int sensorPin = A0; // select the input pin for the potentiometer int sensorValue = 0; // variable to store the value coming from the sensor void setup() { Serial.begin(9600); } void loop() { // read the value from the sensor: sensorValue = analogRead(sensorPin); Serial.println(sensorValue); delay(1000); }

Hello, @Sean-Phillips!

Good to see that you're enjoying your Spresense learning process 🙂

About the interrupts, there are some resources that might help you!
In https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_en.html#_functional_differences, check out the section on Interrupts. It has a lot of important information.

Also, check out the Arduino example that's under "Low Power -> External Wake Up"
https://github.com/sonydevworld/spresense-arduino-compatible/blob/master/Arduino15/packages/SPRESENSE/hardware/spresense/1.0.0/libraries/LowPower/examples/ExternalWakeup/ExternalWakeup.ino

To choose the pins from the Extension board, you only need to change the pin number for a pin in the extension board. If you're unsure about the pin numbers of the extension board, check out the extension board section in our introduction https://developer.sony.com/develop/spresense/docs/introduction_en.html#_extension_board.

Let me know if the material makes sense to you or if I can help you with anything else.

Have fun!
