## What is Honeywell Connected Engines?

The CEDAS Mobile Maintenance Application (CMMA) enables operators to view data from their HTF7K and TFE731 engines. CMMA connects to HTF7K and TFE731 engines through an edge node device called the EDG-100 over Bluetooth. CMMA allows operators to view limited engine data, initialize ECUs, configure wireless networks, and much more!
