Simple BT to UART bridge

Postby x_arrange » Sat May 20, 2017 10:57 am

Hi,
I have some experience with ESP8266 and HC-05. And I was kind of hoping to meet here any analog to this functionality. I have no idea what is HCI, Gatt, BT Classic, Bluedroid, etc, which are used in examples.

What will be really helpful (I guess for lots of ESP32 users) is to have some "getting started" example which will contain something like Arduino's software serial :

Code: Select all

if (uart0.available()) {
uart1.write(uart0.read());
}

if (uart1.available()) {
uart0.write(uart1.read());
}

where uart0 is connected to PC through FTDI(usb to uart) and uart1 is connected to PC (or phone) via BT.

What you are looking for is SPP/RFComm. Unfortunately, while work is underway to implement it, at the moment esp-idf does not have that functionality yet.

Any clue when RFCOMM will be functional? We are trying to put the ESP32 into a product, but absolutely need RFCOMM functionality.

Hi all,
Any update on this RFCOMM module?
Cheers,

We have rfcomm scheduled for release 3.1.

That's good to hear. Do you have more details on this? What exactly will be added and when would that be released?
Cheers

I think this is simply the most expected feature from ESP32 to Arduino users :lol:

I agree with you can't much more.
I think the examples of ESP32 is not friendly and need more demos to teach us how to use it.
