How do I send real time voice data over Bolt to the cloud?
And can I retrieve data from Bolt cloud on MATLAB? If yes, then how?

Hi @gavinf444,

You can not send voice data(audio file) to Bolt Cloud. Why do you need to send the voice data to Bolt Cloud ? Can you write some more details about your project ? Maybe we will provide you some alternate method to complete your project.

Do let me know in case you need further assistance.

Hi @rahul.singh1,
We are trying to build a seismograph project and analyse the vibrations using MATLAB, so if we convert the vibrations into digital data format and send it to the cloud is it possible to retrieve it in real time using MATLAB?

Hi @gavinf444,

Apology for the delay in response, You can connect Bolt with Arduino over UART communication and then you can push your data to Bolt Cloud. You will be able to fetch the data in real-time.

Check this project https://www.hackster.io/garainridyumna/interfacing-bolt-wi-fi-module-with-arduino-6cb7f5 . It explain the connection between Bolt and Arduino.

Also, check this documentation. https://docs.boltiot.com/docs/read-incoming-serial-data

So you can use serialWrite function to push your data to the Bolt Cloud, then you can use the Bolt Cloud API for fetching the data in real-time https://docs.boltiot.com/docs/read-incoming-serial-data

What is the packet size for your vibrations data?

hey @rahul.singh1,
Thank you for the response.
