Data updating upto 241 bytes

[Sudeep R J]

Hello,

I have developed an application that transmits a string as a notification to the phone app whenever there is a corresponding command received from the phone app.

I actually want to send a string of size around 3KB. Now whenever I try to do that using a for loop to send chunks of 20 bytes of data at a time, the maximum number of bytes that I am able to see as notifications is 241 bytes. 

So how do I send the rest of data to the phone app?

Is this something to do with the connection interval?

If so how to solve this and send further data?

Any relevant links or details would be appreciated.

Thanks & Regards

What version of the S112 SoftDevice are you using though? Please check the compatibility matrix to make sure you're using a SoftDevice version that's compatible with SDK v.15.2.

Have you been able to debug the application and/or get an error code?

Best regards,

Simon

Sorry, but  I'm not sure I understand what you're trying to say here. Does this mean that you were able to achieve what you wanted?

Best regards,

Hello Simonr,

No I am not able to achieve what I want. I want to send around 3KB of data as notifications. But I am able to receive notifications only upto 241 bytes. I tried the NRF_ERROR_RESOURCES as you had suggested to me. But from that I am not able to get any notifications. 

This is my problem.

I have shared the code that I have written with you above

Thank you
