How can i connect esp32 to hc05 via bluetooth classic. hc 05 has password.
First you need an ESP32 that supports classic Bluetooth - not all of them do.
I am using esp32 devkit with 38 pin
I moved your topic to a more appropriate forum category @bhavinkateshiya.
The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.
In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Thanks in advance for your cooperation.
Try the following connection (Fig-1):
Figure-1:
Do you know the procedures of testing?
the ESP32 should support Bluetooth Classic communications OK
try running File>Examples>BluetoothSerial>SerialToSerialBT
what host microcontroller is the HC-05 connected to?
EDIT: thinking again try running try running on ESP32 File>Examples>BluetoothSerial>DiscoverConnect
Hc 05 Connected to weight scale, which continuously send weight data. i want to receive that data to esp32.
Show the connection diagram between Weight Scale and HC-05 and the whole picture of the Weight Scale along with its Bluetooth device.
I want to connect like this
As HC 05 has pin it can't be able to connect to esp32. I tried all example, but not able to connect both together
First check that yo can pair the Bluetooth with your Android Phone's Bluetooth Terminal and then try with with ESP32 using another BT.
Is that Bluetooth is an integral part of the Weight Scale?
yes i able to connect with android phone's Bluetooth Terminal and yes hc 05 is integral part of weight scale
I read this doc regarding bluetooth serial, i think now there is no option to connect via fixed PIN
1. You connect a HC-05 Bluetooth with ESP32 as per Fig-1.
Figure-1:
2. Follow post #4 of this tread to operate BT1 of ESP32 and BT2 of Weight Scale as Master/Slave.
I have found TX & RX point on weight scale PCB and connect another esp32 to TX & RX of weight scale, now i can pair two esp32 via Bluetooth.
It is better that you do not temper the PCB of the Weight Scale; rather, go on Master/Slave operation. Your equipment are safe.
