How to control the display and non-display of sensor values in Arduino using Bluetooth?

Asked 2022-Mar-22 at 09:06

I have a sensor that connects to the body and displays muscle signals.
In the setup guide of this sensor, it is said to upload the following code on Arduino, and when we open the Serial Monitor, the sensor values start to be displayed.
Now I want to control the display of these signals using Bluetooth.
So that when I click on the start button in my App, Serial.print() will start working. Also, when I click on the Stop button, the display of these signals and numbers will stop.
Sensor setup guide is this :

QUESTION

Turn relay on from Bluetooth for certain amount of seconds

Asked 2022-Mar-14 at 11:06

I am working on two way communication between arduino and android phone. Currently everything is working, however I have couple of issues I have been trying to solve recently.

How I can ignite ignition for 5 seconds? I mean if IgnitionPin is on HIGH, run it for 5 seconds then automatically turn off? There is an easy way with delay, but it will not work in my case as don't want any other delays to slow up my script.
I am using Arduino Uno. I want to start my Arduino with pin in OFF position. Why pin 10 always turns ON then shuts down, even with digitalWrite(IgnitionPin, HIGH); I have tried other pins and they work fine -> turned OFF on start.

Arduino sequential softwareserial.print() overwrites itself

Asked 2021-Sep-10 at 03:06

I am still having problems with writing from HM-11 bluetooth from DSD tech back to a phone app (Serial Bluetooth Terminal 1.35 on play store).

My code currently has a large string cut into 2, as per the result of my last post, due to BLE havving a maximum buffer of about 252 bytes. The issue I am facing is the fact that the dealy(450) is currently required to prevent gibberish.

From what I have gathered, this is a limitation of the BLE messaging system. There is no such thing as serial communication for BLE, everything is type packet based. Somehow the app on my phone is able to communicate and send it packets up to 252 bytes long and disguise it as serial such that it is not noticeable. After this much, BLE is incapable of sending this much data, and the buffers gets messed up. Someone with more BLE experience may be able to explain, but this is my result.

To remedy, swap over to regular bluetooth (HC-05, or HC-06 or equivalent, not BLE) which only support serial. As there is no such thing as a typed packet, it works. I just swapped out the component (exact same pinout, so 1 for 1 swap) and issue resolved. Thank you to those above for their suggestions, but this turned out to have been the problem.

QUESTION

Arduino SoftwareSerial Write bluetooth cutting off static text message write back

Asked 2021-Aug-29 at 07:09

I am fairly new to Arduino, so this is likely to be some very simple C/C++ issue that I don't know

I am working on a RGB LED Cube that I made from parts based off of GreatScott's video. It works fine. I decided to improve wahat can be done with it by adding Bluetooth. I am using an HM-11 from DSD tech.

I am able to write commands from my phone to the arduino over bluetooth with no problems, and I use that to swap modes.

The issue I am facing is when I try to write back to my phone over bluetooth. I am sending back help text over bluetooth, so that whoever connects to it and sends help can find a list of supported commands. Using SoftwareSerial, I have the following (snippet of problem area):

It looks like you are able to send about 252 bytes before it gets truncated. That figure seems to be about the maximum data size in a BLE packet.

There is some discussion around the maximum data size at: Maximum packet length for Bluetooth LE?

BLE "long read" and "log write" functionality include an offset along with the handle in the request so that the characteristic value can be read/written in successive chunks over multiple request/response pairs. I am not aware if the Arduino library and HM-11 hardware support that functionality or not.

Simple HC-05 bluetooth android communication

Asked 2021-Feb-13 at 17:53

Im trying too simply communicate between my android phone and my arduino using the HC-05 bluetooth module.

While my module works and i am able too send and receive data on my phone, the data of my btData variable seems too instantly get lost after being received. On my android app i get the input data output like written in my code and then instantly an empty output/line.

Writing "1"/"off" into my console does not trigger my if(btData == "1")... part of the code.

I have attached my code, aswell as the android terminal and my arduino HC-05 connection.

Hopefully someone is able too help since i cant find any error.

Could it be that the data that is being sent has a new line character at the end of the string?

This is why you are seeing the empty line after the data that you have sent.

QUESTION

Arduino, input from BT-Module is stacking and added

Asked 2020-Jun-06 at 05:23

I wrote an Android App which sends data to an Arduino via Bluetooth. The Connection works fine and is pretty stable. The only thing that bothers me is that the input from the serial connection is not how I would like it to be. This is hard for me to explain but every time I send a new command, the ols command is still in the serial input so that the new input is not recognized by the Code I wrote. Maybe this is just a very dumb issus but I just dont know what I can do to fix it. I will post the Code and the Output here so that the problem is visible.

I am using SoftwareSerial (here as BTserial) and it feels like I have to clear the buffer of the connected HC-05 module or the serial buffer and I tried so many other solutions but none of them worked, maybe I just don't understand what the issue is here.

My code:

It's not the Serial buffer that you need to clear. It's the String that's holding the command you read. You have to clear that out. The serial buffer gets cleared out as you read the characters from it.
