Re: ESP32 with ESP-IDF Classic Bluetooth - Mobile Phone - Serial Communication

Sorry for the long delay. Below is "my" code. I used initially the ESP-IDF sample code example_spp_acceptor_demo.c and modified it. This is not clean code, I didn't have time to clean it up yet. But it works. I pair my phone with the ESP_SPP_ACCEPTOR (ESP32 running with this code). And then I use on...

UART receiving and processing text lines - not bytes

I connected an Arduino with an ESP32 with the UARTs. I looked at the ESP-IDF API and examples and I see how bytes can be send and received. I am sure I could use this also to send and receive text - with some extra work. But maybe there is an easier way to do this and this is what I am asking here. ...

Re: ES32, ESP-IDF and UART

I read only part of your post and maybe what I will write has nothing to do with what you want. But maybe … I used an OBD adapter on my KTM motorcycle. The data was sent per Bluetooth from the OBD adapter to my mobile phone. On the phone I used Torque App to see the data. And then I wanted to see mo...

ESP32 with ESP-IDF Classic Bluetooth - Mobile Phone - Serial Communication

I was looking for sample code to create a simple application for serial communication between the ESP32 and a mobile phone. It took a long time before I figured out how things work. Here is some information - for a start without code. I looked at the ESP-IDF BT-SPP-ACCEPTOR demo https://github.com/e...
