I'm a programmer, more from the software side but I do have hardware working knowledge too. I've completed the Arduino Starter Kit's 15 projects, Now trying to build some things with ESP8266 and HM-10 BLE.
I was able to connect ESP8266 to my network and start a TCP server too via AT commands(using Arduino's Serial Monitor and FTDI 232RL USB to TTL converter)
I also have a HM-10 Bluetooth Breakout+connector board (Its based on CC2541 by TI (visible on the SMD chip)) brought from here.
Using the same setup I was able to issue AT commands successfully for ESP8266. However I tried many things, different baud rates and \r\n combinations; I just couldnt get the HM-10 to acknowledge my AT commands.
Arduino +5V --> +ve input of LDO regulator --> 3.3v OUPUT to Vcc of HM-10 Common GND for LDO regulator input and output pins, FTDI 232RL and HM10 FTDI TX --> voltage divider (1k ohms --> connection output to HM 10 RX --> 1k ohms --> 1k ohms --> GND)
There is no code/sketch as of now. I'm just trying to hook up the HM-10 BLE chip. I can pair my Android phone to it but that's not the concern here.
The concern here is I cannot configure the HM-10 using AT commands.
The HM-10 does not reply an "OK" acknowledge for my "AT" command. Nothing happens in the serial monitor after hitting enter. Just a blank screen.
Is there a way by which I can determine what baud rate to use and what combination of \r and \n?
What am I missing here?
