I am trying to collect IMU data from two Arduino Nano 33 BLE Senses at the same time over bluetooth. I have been successful in collect data from one sensor over Bluetooth and have been able to implement this in app designer as well. I hope to be able to collect from both sensors at once. I have tried to use the Parallel Computing Toolbox, but have not been successful. I have some of my collection code for one sensor below. I am able to get two sensors connected in matlab over bluetooth, but I don't know how to collect from both at once.

a=arduino("EAD91D0297DC") %Connect to the Arduino over Bluetooth

lsmObj = lsm9ds1(a,"Bus",1,"OutputFormat","matrix","SamplesPerRead",250) %Change output format to Matrix

acceleration=[]; %preallocate arrays

angularVelocity=[]; %preallocate arrays

magnetometer=[]; %preallocate arrays

counter=1;

[acceleration,angularVelocity,magnetometer,timeStamps,overrun] = readData(lsmObj)

function [acceleration,angularVelocity,magnetometer,timeStamps,overrun] = readData(lsmObj1)

counter=1;

% Loop continuously to read data from the device

while counter<1001

% Read the acceleration and angular velocity data

[acceleration(counter:(counter+249),:), angularVelocity(counter:(counter+249),:), magnetometer(counter:(counter+249),:), timeStamps(counter:(counter+249),:), overrun] = read(lsmObj1)

counter=counter+250;

end
