Arduino Nano AT Command Not Working

I have worked with different Bluetooth technologies on different microcontroller platforms, Please contact me so we can debug the code correctly. Thanks.

Hi, I will help you in setting AT commands for your bluetooth to change its configurations. I will use team viewer to help you out right on your hardware alao guide you how to enter in AT commands mode. It will help you if yoi want to change, name, password, master slave mode etc. Thank you

Hi There I have checked your project description and understand everything. I am very confident that i can do this project perfectly. Thanks

I can do your job.

How r u?Bro,,Its me Imad,, Have done 200+PROJECTS REGARDING MATLAB, ARDUINO, VB.NET, PHP, HTML, PCB DESIGNING and much more. Some of the projects are as follows. 1. NEXTION LCD Based bike monitoring and Control System. 2. esp 8266 Home automation and monitoring. 3. Anti theft car system and gps locator U will feel brotherhood.

Hello, I'm very skiled with Arduino and Bluettoth modules in general. I think that I can help you solve this issue very fast. Best regards, Radojica Berak

Hello, I'm Joao Patricio, I'm an Electronic Engineer. I work since 3 years ago with Internet of Things and other microcontroller projects. I work with circuit's design and firmware develloping Usually i Work with pic, ATmel, Arduino (Uno, Mega, Nano and Due), ESP8266 (boards like ESP12 and NodeMcu) For my firmwares I use C/C++ and Lua Script About Your project: 1 - the wiring. The HC-05 serial communication pins operate at 3V3. so to connect to the Nano, you need a voltage divider. NanoRx ---- HCTx NanoTx --- (voltage divider) --- HCRx. Otherwise, HC-05 may be damaged. 2 - Assuming that point 1 is ok. To respond to AT commands, pin 34 must be high (pullup resistor to 3V3). This pin is relatively hidden on the side of the plate. Put it on high level and restart the module. 3 - When in command mode, the baudRate of HC-05 changes to 38400. No matter what you initially set in the code, this is the default of it when restarted in command mode I hope it answers your problem.

A proposal has not yet been provided

I’m a Electronics Engineer with long experience on Arduino boards

I have done several arduino and bluetooth based projects. I am sure that i will sort your problem. Lets talk over chat and discuss it.
