Today I bought HC-06 and it work @9600 pbs. So can you post code how to change it to whatever it need . I try change delay but same results.

Glad it works with HC-06 Please scroll up to reply #15 and download the HC-06 config tool
I own HC-05 and HC-06 cards and they both work flawlessly @57600bps
Did you make any change in "Option for advanced users" ?? Let me know your current settings for - Refresh interval - Time out count
Please reply
@Bob1943
Still only xxx showing bottom left
Are you referring to the joystick position field at bottom left of android device screen ?? :astonished: This should indicate joystick position at App start up, even before any connection It should read (-100,-100) for South West position and (100,100) for North East position
Interesting point is that button B5 stays locked the same as other buttons until pressed again to release. (I did notice at one time it did act like a push button – maybe that was when data got fed back).
This is normal behavior when not connected
My only problem now (apart from error in BT board configurator mentioned above) is the failure to get a signal from Arduino to Android.
- You can follow joystick position and buttons state on you Serial Monitor
- Datafields don't update, B5 is not in "push" mode Correct ??
Answers to 9 question in reply #197 1..Version v4.0.4
I was talking about App version, should be V4.0 OK ??
the AT command AT+UART? returned: 57600,0,0 Is that OK?
Yes According to documentation Param2 = stop bit: 0->1 bit 1->2 bits Param3 = parity bit: 0->None 1->Odd parity 2->Even parity Arduino serial is 8N1 (1 stop bit, no parity)
UNO TX LED flashes about every 2 seconds and whenever a button is pressed. When the joystick is moved it constantly flickers,
This reflects the data flowing from Arduino to Serial Monitor
then after about 10 seconds of continuous joystick movement the TX LED locks on. Opening the serial monitor window seems to return it back to normal.
Strange :relaxed: :relaxed:
Did you change any setting in Advanced options ?? Try "reset Option" to restore initial parameters EDIT: also set Refresh interval @100ms, Timeout count @every 10 intervals
Finally let me have a link to your specific BT board
Data flow from Arduino to Android problem SOLVED
I am using Joystick BT Commander on an Android Tablet. This allows Apps to be closed by swiping the minimised app icon off the screen. This was the problem.
When I closed the App by using back button (hairpin arrow) and confirm “Total RC Commander - close this controller” and then re-open the App it works OK. Data received back from Arduino and Button 5 is in push mode. Apologies for inconvenience and thanks for your time. It is great to see the care and level of attention that you provide to the users of your App. Again many thanks - Brilliant App Bob

Thanks Bob for the good new and the kind words 8)
I am investing time because this App should bring a lot to the Arduino community It is a universal remote for most projects, using wide spread (Android) technologies. I told my friend to download the App and within a minute he took control of my RC tank He was rather impressed :astonished: :astonished: :astonished:
During my support session, I did some interesting stress tests yesterday. I tried various data refresh interval at different baud rates and found some minor glitches. Please use AndroTest_V14.ino
#define VERSION "\n\nAndroTest V1.4 - @kas2014\ndemo for V4.X (6 button version)"
// V1.4 improved communication errors handling
// V1.3 renamed for publishing, posted on 09/05/2014
// V1.2 Text display ** not backward compatible **
// V1.1 Integer display
// V1.0 6 buttons + 4 data char implemented
** The message exceeds the maximum allowed length (9500 characters) **
See next message
This updated sketch features optimized timing and better transmission error management Again, make sure your BT board is set @57600bps Avoid using 25ms refresh interval and continuous timeout count, that's too much data I am also preparing V5.0, with a pure ASCII communication protocol
Some thoughts
Where is AndroTest_V14.ino – only some lines showing?
In the Android app can you recognise when the app has been closed ‘illegally’ and act upon that action next time the app is opened. Might make it idiot proof.
When you first touch the yellow joystick dot, it immediately moves to the centre of the touch point. This changes the xy numbers – most noticeable when you touch the edge. (I want to control two servos but don’t want them to move until the joystick is moved intentionally). Can the touch point be recognised without moving the yellow dot?
What do I need to change to alter the data fields fed back to the Android and can it be coded in “Your code here” areas in the Arduino sketch. I am doing number crunching on Arduino from Joystick positions and would like to send three values back to android.

To send back three values to Android (data_1, data_2,data_3,) just modify sendBlueToothData()
void sendBlueToothData() {

mySerial.print((char)0x2); // Start of Transmission

Hi, Thanks for information
The swipe-to-close feature is about 40 seconds into video at this site: http://blog.laptopmag.com/9-awesome-android-ice-cream-sandwich-tips
This method is what was causing problem about no data from Arduino to Android. I wonder if this happens with other users?

I can’t replicate the “swipe” problem both on Galaxy Tab3 tablet and Motorola G phone (V4.4.2)
Please let me have a step by step procedure
I am using a 7 inch tablet which doesn't have phone but allows multitasking. My Samsung GT-S5570 phone won't recognise the HC-05 so I can't test on mobile phone. However, the link below shows how to swipe on Galaxy 3. Hope this helps. I think all Android tablets have swipe-to-close so others may also have a problem. If you want I can video the actions. Just let me know

(anyone know why my Samsung GT-S5570 phone won't recognise the HC-05)

Hi Kas, This version V4.1 works fine. Wherever you touch on the yellow spot is returned as coordinate 0,0 (x,y) which is exactly what I was looking for. No jumpy servos anymore. - Many thanks
A couple of comments on Joystick BT Commander.
As information can be sent from Arduino to Android, is it possible to use the Android like a Serial monitor to display this information with rolling values - just like the USB to computer screen. You could give the option to change from Joystick to Monitor to make space on the Android screen. An option to rotate the Android to make a deeper window would help, and an added bonus would be to have a button to pause the display if required.
Can the Arduino Bluetooth code be put into a library so the bluetooth device can be connected and used as a monitoring/commander tool. This would make the Arduino coding for the main applications more visible.
Just a thought!!!

Thanks, I will include this feature in V5.0 (pure ASCII protocol)

Android Bluetooth joystick is a small footprint App (78Ko), its only task is to emulate a joystick ;) There are very good App for serial monitoring, BlueTerm is one of those
My Samsung GT-S5570 phone won't recognise the HC-05 so I can't test on mobile phone
Try sending AT command
AT+CLASS=1
Should work
@Topicja
Hi Kas I really like your excellent android app but after last update i cannot get it to work. I tried to rewrite my program but i don't receive any data. Could you please send me apk file of older version? Version 3.1 was working well for me. My e-mail address is xxxxxxxx@xxx.com
Thank you for your response and your willingness
I could recompile V3.1, but it makes much more sense to have your own program fixed and working Joystick transmission has not been modified and should work, does it?? Please let me have your original Arduino sketch, I will fix it for you
@all Should you encounter same difficulties, please contact me via PM
Sorry for late response. My problem was in bautrate and also you must press 3.rd button to get work … so yust overwrite setbuttonfeedback=false to setbuttonfeedback=true and it work for my.
@Topicja

I will send you the modified sketch tomorrow evening There are too many transmission errors at 9600 bps Please, in the meantime, configure your BT card at 57600 bps
Are you able to do it by yourself ?? Otherwise, let me have a link to your specific model
For those who still have a Bluetooth card configured @9600bps, please add a one millisecond delay after the second "while(mySerial.available())"
void loop() {
if(mySerial.available()) {
delay(2);
cmd[0] = mySerial.read();
if(cmd[0] == STX) {
i=1;
while(mySerial.available()) {
delay(1); // <This will prevent while(mySerial.available()) to return before the complete data frame is received I have modified AndroTest V1.4 to reflect this modification (now Version 1.41)
I only work @57600bps and never bothered checking lower data speeds :blush: Thanks Topicja for bringing this point to my attention
A sweet thought for the Microsoft developers who deal with thousands different hardware configurations and get bashed by users because... "it doesn't work on MY specific setup" ;)
