Pro mini is not working through bluetooth control

Using Arduino Project Guidance
1

Hi guys im trying to send data from phone to pro mini through bluetooth, but look like the pro mini does not receiving the data that i sent. I have try to use arduino uno and it is work. Is it promini cannot read serial?

2

Please provide some clues to your project such as a schematic and the full sketches that you are using

For instance, which pins on the Pro Mini are you using for Serial and how do you know that it is not receiving the data ?

4

is there a problem with pro mini spec and serial on pro mini?

5

Not as far as I know

If I were you I would start with a simple sketch that prints the characters that it receives from Bluetooth

6

i have use serial.print on arduino uno, but pro mini is more complicated because need to use usb ttl. when open the port will always busy warning pop up

7

Pro Mini and UNO use the same processor, ATMega328P.

Sorry, but I don't understand what you are saying

Which pins are you using for the Bluetooth serial connection on the Pro Mini ?

Why did you delete your code from this topic ?

none havent tried bluetooth from pro mini?

11

No from the Pro Mini, to the Pro Mini

It looks like you are using pins 8 and 9, but I don't understand what you mean by not being able to print what you receive

12

ahh thanks i just remember i move the rx and tx to pin 7 and 8. ill try to fix tomorrow at workplace

13

Could you please explain how this is supposed to function?

All your animations block, that is to say they run to completion, whatever that mean in each case.

So the response to user input may be sluggish? And seem like it isn't doing anything or not what you want?

Anyway, I made this just to watch what they all do:

It just runs them one after the other and leaves out the comms/UI stuff.

I have no energy to untangle just how the user is supposed to control this, so help me.

TIA.

wow, what a great apps you use there, but usually the mistake is, in arduino uno i use software serial at the rx and tx pin at 8 and 7, different with pro mini which where i use the tx and rx pin is default. That is why i have revise my code not using software serial and serial.begin(9600). So basically the mistake is regarding technical circuit

15

regarding how th user control is through apps, i think u cannot control from there.

16

Thank you for the clarification.

17

Why ?
Using the Rx and Tx pins with SoftwareSerial is not a good idea because they are used by the normal hardware Serial interface

18

my uno tx and rx pin 0,1 pin having a problem that is why i use software serial

19

Those pins are for hardware serial.
