hello i am making an led controller for my speakers and need to program the esp12F over bluetooth using an HC-05 module.I am using the version without the breakout board so that i have the rts pin.
The problem is that i only have rts and cts pins but i need rts and dtr
Hello gracz
We need some additional information.
Post your sketch, well formated, with well-tempered comments and in so called
code tags "< code >" and a detailed circuit diagram to see how we can help.
i just need to upload it when i make it and i need to know is it okay to use cts as dtr
i am working at the sketch slowly since i am focused on learning android studio kotlin since i want to make a custom app for it
Strange requirement. The ESP12 is normally updated OTA (via WiFi).
Having a 2.4Ghz BT reciever next to a 2.4Ghz transmitter might not work.
There's lots of info on the net about programming an ESP8266 OverTheAir.
Leo..
you know but i don't want to lets say upload code without OTA by accident and have to open my speakers and connect an ftdi to the board to flash it.And i will not be using wifi
Not sure what you're saying.
OTA is flashing over WiFi, and is already built-in.
You can choose your ESP right from your PC/laptop, as if you choose a COM port.
No opening of the speaker, and no FTDI needed.
Leo..
so i don't need to include OTA in my code?
plus i still need bluetooth for the phone app
An ESP32 could have been a better choice.
It has WiFI and BT.
Leo..
But it is bigger
And even an esp8266 for RGB leds is like shooting a mosquito from a canon.the esp32 would be like a tank.also i think the esp8266 has a more acurate adc
