Hi,
have you tried using the 'unsecure' MQTT port 1883?
Using this one you should not need a certificate or PSK.

Also, did you check this part of the documentation:
https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_en.html#_to_convert_image

It talks about the resizeImageByHW() and clipAndResizeImageByHW() functions.

Good luck!

Hey, @jdwbmc
Did you come from the Hackster discussion page?

Please check the connection between your main board and your extension board. If the connection is not properly done, you might have issues with the SD card.

if you did come from the Hackster discussion page and have already tried all the tips on those topics.. Then I think you might have a hardware problem with your sd card connector. Do you have a access to a multimeter?

Do you mean that if the loop function is like below then the program works?
(plays() outside if statement)

void loop() {

sensors_event_t a, g, temp;
mpu.getEvent(&a, &g, &temp);

x = g.gyro.x;
y = g.gyro.y;
z = g.gyro.z;

plays();

myFile.close();
myFile = theSD.open("ask_help.mp3");
go = true;
}

Hey, @karlbot
I have been able to download the file in a Mac computer. Maybe it was just a temporary issue.

@dxc-fl

That's interesting.
I still haven't found out why this is the case. I'll continue this investigation internally, but let me know if you have any progress in the issue.

Hey, @Bhalaji-Kharthik
I'm having some technical issues with my IDE and wasn't able to try and reproduce your structure.
Were you able to solve your issue?

One thing you can try to do instead of changing the SDK entrypoint is using the start-up script as described in https://developer.sony.com/develop/spresense/docs/sdk_tutorials_en.html#_usage_of_start_up_script

Hey, @Thaïs

https://github.com/sonydevworld/spresense-nuttx-apps/blob/new-master/examples/alarm/alarm_main.c
Please take a look at this example and let me know if it helps in your project.
You can pass the alarmid as an argument to this example. Also, to enable multiple alarms, you can change the CONFIG_RTC_NALARMS config.

Closer look at the setmode portion of the code. Starting in line 385.

Hey, @JinDEV-0-1-1!
What is your OS and your python version?

Hey, @RomainPC-0-1-1-1-1-1-1

It's okay, I don't see any problems with that. reserved0 and reserved1 are not being used in this current version of the SDK. So yes, you can use those spaces freely.
It is important to note, though, that if you were to eventually update your SDK to a newer version, you'd have to check if those spaces are still not being used.

Hey, @Stanton

We do have one example.
https://github.com/sonydevworld/spresense-nuttx-apps/tree/fb3f4e3e48fb915ddcb9224d374f666d2de85aff/testing/smp

Configuration for that would be from smp_asmp example.

@CamilaSouza

Thanks for the info on the Flash.
Also for pointing me to the example for polling. I had a look at it and interpret it as an idea to communicate between modules that have been started by different threads.

To use the Arduino IDE was my self-imposed guideline for my project. However there are limitations, so I do not always stick to it. So it is fine to follow SDK examples.

I think this topic can be marked as soved.

@Larry

OK it is more complex than I thought.
I only have a jlink device and no cmsis-dap device. So I am stuck. I will put this topic aside for now. Please let me know if you have more luck.

For your reference
https://developer.sony.com/develop/spresense/docs/sdk_set_up_ide_en.html#_ice_debugging

The configuration needs to be modified to work with Arduino. The instructions are only for the Spresense SDK.

Hey, @jlutzwpi
That's so nice!!

Keep up the good work.

@karlbot

I had to set the analog gain to max to get anything hearable. Maybe you can give it a try?

theRecorder->setMicGain(210)

I am using another microphone though
https://www.switch-science.com/catalog/7369/
https://github.com/autolab-fujiwaratakayoshi/2mic_kit_for_spresense_LTE

Otherwise difficult to say. I just tried recording only to SD card and paused using audio until there is an answer about the opus codec.

@Larry
Of course! I'm happy to help.
