You will save yourself a lot of headaches by sending the data in ASCII instead of binary: bluetoothSerial.print("RMSCurrent: "); bluetoothSerial.println(RMSCurrent); Of course, you will then have to parse the data stream on the Python side. If you really want to send binary data, then be aware that the write() method you are using is intended for ...

I don't know what the time.sleep(4) statement fixes, but you could try moving the to the top of the loop instead of the bottom, so it precedes the first read. At the bottom of the loop, it's first execution comes after the first read.

You might want to try sending the data in a packet delimited by unique characters, e.g. { and }, similar to the JSON format. The NMEA GPS standard uses $ and '\n' to delimit messages. Here is an Arduino non-blocking C++ algorithm which builds upon Majenko's readline() example to read a packet. It returns true when incoming data has been accumulated into a ...

I think you want something like Blink Without Delay, but with more tasks. Here is my interpretation of your description which extends Blink Without Delay by adding three more tasks to: read the accelerometer perform "just once" perform "also just once" I've added several Serial.print() statements to give a running commentary on what's ...

Update: After trying numerous codes, I was 💯 sure that it wasn’t a software problem. I then removed the Hc05 module from the circuit, and I was able to put it in AT mode(this means my module is working fine). This leaves only one possible problem I.e the circuit. I used a multimeter to measure the voltage between Hc05 RX and GND. I got 1.8v(but how?). After ...

The Device Is Not An Arduino Device (Uno,Mega,Nano,Mkr,etc)and arduinoBLE was made only arduino devices with builtin bluetooth

if you are using an Arduino, I recommend you to use the BPlib, it's a free arduino library that contains functions that are similar to the Keyboard.h. The following link is from the Arduino website: https://www.arduino.cc/reference/en/libraries/bplib/ When you download the Lib, take a look at the examples given by the creator of the Library, all the example ...

There is an issue with the way in which the data is sent and received because it assumes the transmission will remain perfectly synchronised for the lifetime of the programme. Consider what would happen if one byte were to be dropped due to a communication error – the x and y data would be swapped for further transmissions. Original Sender void loop() { // ...

You can find the answer in the Bluetooth connection to HC-05 paired but not connected Step; 1.Once you have paired the HC-05 as you've described, bind the device by entering; sudo rfcomm bind 0 "MAC address" 1 2.To trigger the connection & display the data using minicom, run; sudo minicom -D /dev/rfcomm0 You'll notice that port /dev/rfcomm0 ...
