I have recently started working (no previous experience of working with BLE) on BLE2 click module (RN4020), I could successfully connect TTL-USB cable to my laptop and could communicate with the module via the MLDP mobile application.
However, now I would like to use it in UART mode and as per the link: http://microchip.wikidot.com/ble:rn4020-operating-modes , I should be working in MLDP mode, i.e. CMD/MLDP pin should be connected to Vcc, is my understanding correct?
Also, I would like to clarify on this point which is mentioned on the same webpage: "To enter Command mode, set the WAKE_SW pin high." Is it WAKE_SW pin that should be held high or CMD/MLDP pin should be held low?
Also, can anybody provide information regarding the set-up required to interface the module with MSP430 mcu, can i directly connect the module to MSP430 after performing the following steps using TTL-USB interface:
+ // echo on SF,2 // perform complete factory reset SS,C0000000 // enable support of the Device Information and Battery services SR,00000000 // set the RN4020 module as a peripheral R,1 // reboot to apply settings
