The integrated Bluetooth Low Energy (BTLE) stack and onboard support for the common SIG low-energy profiles speeds time to market while ensuring Bluetooth compatibility, eliminating expensive certification costs and reducing development risks. The module is also pre-loaded with the Microchip Low-Energy Data Profile (MLDP), which enables designers to easily stream any type of data across the BTLE link.

The RN4020 is a stack-on-board module and can connect to any microcontroller with a UART interface, including hundreds of PIC MCUs, or it can operate standalone without an MCU for basic data collection and communication, such as a beacon or sensor. This standalone operation is facilitated by Microchip's no-compile scripting, which allows module configuration via an ASCII command interface.

Hello, i am trying to establish data communication with rn4020 microchip module, so far i was able to connect to the module but mldp mode is not working. Simply asserting the CMD/MLDP just as described by datasheet is not working.

This is my initialization code:
puts ("SF,1,2");
puts ("SR,20060800");
puts ("SS,00000001");
puts ("R,1");

initialization and connection is successful but as i mentioned before, sending data transparently is not working.
