How to increase throughput for BLE GATT profile?

Hi there,

I am currently working on a custom GATT profile for constant data streaming. I have to keep to GATT because I need multiple attributes to keep track of different data and for sending commands. So far, I have reduced the BLE connection interval to 7.5ms with latency 0. The fastest theoretical throughput is ~133Hz. However, I have read somewhere (pardon me but I have forgotten where I have seen it) that I can actually send up to 4 packets per connection interval, so that's ~133Hz x 4 = ~533Hz. Is this possible? If so, anyone has any idea on how can I achieve this using the current S132 SDK? Very much appreciate your input! Thank you in advance.
