I'm transmitting serial data from a sensor on my Arduino simultaneously to my laptop via USB and to a terminal app on my phone via a genuine HM-10 BLE module (onboard a Linksprite BLE Shield). At 9600 baud, the BLE module was transmitting all of my data to the phone's terminal app without issue. I just figured out how to increase the HM-10 module's baud rate to 115200 (for reference, by sending it an AT+BAUD4 command at 9600 baud from the Arduino IDE console via USB, and then uploading a new sketch to the Arduino with both the USB serial and BLE serial baud rates set to 115200). The data is being received via USB serial flawlessly, but the data received by the terminal app on my phone via BLE appears to be missing chunks of data - and I have to try to connect to it 30+ times to get it to properly connect. Is 115200 baud too fast to transmit data via BLE? Is there any way to make sure all of the data is properly sent via BLE without slowing the program down too much? 9600 baud is too slow for my application, unfortunately. I should add that I am using an Arduino M0 pro and the BLE is connected via hardware serial (Serial1) and not SoftwareSerial as would need to be done on the Uno, if that makes a difference. So I purchased a few HC-06 bluetooth slaves from Amazon earlier this week, and I've spent the afternoon trying to configure them with the help of a couple of tutorials. The Goal: Change the Baud Rate of the HC-06 to 115200 (the default sketch upload rate for the Uno) so that I can remotely reprogram my Uno. The Approach: The code I'm using, along with the problem I'm having can be seen. The code is just copy/pasted from the tutorial I've been using. Now, the tutorial lists the commands needed to change the baud rate (AT+BAUD#). I've successfully changed the rate to several different rates without any issues (57600, 19200, back to 9600). The Problem:But when I change it to 115200, the Arduino can no longer read the responses from the HC-06 correctly. Instead of getting a confirmation 'OK' in response to the command 'AT', I get the kinds of bizarre characters you usually get when your baud rates don't match. But I can't work out why that would be happening to me. The Code looks OK, and everything seems to be functioning. I know that the serial commands I send are getting to the HC-06 intact because I can send commands to reset the rate to 9600.

It's just weird to me that the Uno can talk to the HC-06, but can't correctly read back it's responses. Maybe there's more interference at that much higher rate? I've done some digging, but I can't come up with a likely sounding explanation. Any ideas why that would be? Thanks in advance for any tips, you all are amazing! ![]() TL;DR Using a specific baud rate is giving me screwed up messages, but only going from HC-06-->Arduino-->SerialMonitor, and not SerialMonitor-->Arduino-->HC-06. *edit-formatting • • • • •. I am also playing with the HC-06 module and found the same issue when setting the baud rate to anything higher than 57600. I'm using a TTL-232R cable to communicate/change settings. I'm thinking at this point, it's nothing to do with your code. Just a limit of the serial link from the module. It might have to do with the signal levels as the HC-06 are a 3.3v level and the arduino/TTL cable are at a 5V level. Make sure the baud rate of your Bluetooth module matches the baud rate in your Arduino sketch. All examples uses 57600 baud ( Serial.begin(57600) ), so if you use a BT module with 115200 baud you have to change the 57600 to 115200 in your Serial.begin statement. Upload the sketch to your Arduino.
