Q:

Does the dual BLE module RN-4677 from Microchip use the MLDP profile

Does the dual BLE module RN-4677 from Microchip use the MLDP profile? I have searched in all datasheets but I couldn't find the answer. The datasheet says only:

In addition to SPP for Bluetooth Classic connectivity, the RN4677 introduces a private Generic Attribute Profile (GATT) service for serial data transfer between two BLE devices. This BLE data streaming service provided in the RN4677 is named “Transparent UART”. Therefore, the RN4677 is a Dual mode Bluetooth module, which supports both Bluetooth Classic and BLE serial data connectivity.

But in some other datasheets of Microchip e.g. for the RN4020 it say's

For all supported profiles and services, the RN4020 module can be configured to act as server and client roles at the same time. Furthermore, the RN4020 module supports the private Microchip Low-energy Data Profile (MLDP), which provides an asynchronous serial data connection between two RN4020 devices.

So is that the same or are there differences? Thanks!

A:

It seems that the MLDP is implemented in the RN-4677.
