What does status code 13 in onCharcteristicRead mean?

im making a BLE application using the CIQPi as a base. I have a python Bluetooth server setup on my raspberry pi and get status code 13 whenever I make a read request to the pi. Any help is appreciated

How much data are you sending from the pi? The limit is 20 bytes or so with CIQ.

Just one byte. The only way the data comes through with a status code of 0 is if I send an empty list

Sounds to me that on the pi you can't sending the data correctly. i use node.js with my pi apps. How do you do it with python? What do you see if you try to read that characteristic with something like nRFConnect? Do you have things defined correctly in the profile manager for your CIQ app?
