Getting"Input size exceeds 20 bytes, maximum input size 20 byte"

I am getting this error when using BLE send block from Simulink SupportPackage for Android sensors. I am trying to compare the outpur of Camera block and pass a constant using a switch to the BLE send block

[Walter Roberson]

I would have thought a camera block would return a fair bit of data, and I would have thought that it would tend to have noise, and that therefore comparing two frames for equality is unlikely to work ?

Anyhow, it sounds like you have too much data for Bluetooth Low Energy.

Hi Satyendra,

Maximum no of bytes you can send through BLE Send block is 20 bytes i.e Input of BLE Send cannot exceed 20 bytes. Make sure Input is less than 20 bytes
