Softwareserial Library Download
SoftwareSerial Library Download: SoftwareSerial is included with Arduino Real UART Serial The hardware UART Serial port should always be used, if possible, before considering SoftwareSerial. On Teensy, the hardware UART serial port completely separate from the USB port. On Arduino boards, the main hardware serial port is used for programming and sending messages to the Arduino Serial Monitor. Both of these libraries are available from the Arduino Library Manager, under the menu Sketch- Include Library- Manage Libraries. SoftwareSerial is very inefficient, because it disables interrupts for long periods of time. It cannot send and receive at the same time. /adobe-acrobat-8-pro-key.html. ESP8266 12E NodeMCU & SoftwareSerial. Test To verify the operation of the softwareserial library, I downloaded the library for esp and I have temporarily replaced the serial software version for arduino. Conclusions Although this is a basic test, it requires more complete tests regarding the configuration of more serial serial ports. The idea is to use this library.

Unfortunately, I've tried and tried to get the two to communicate, with no luck. I figured out how to change baud rates on the Bluetooth module using the Arduino Serial Monitor, so I knew I could send and receive fine between the Bluetooth module and the Arduino .. I could connect from my Android tablet to the Bluetooth module, so I knew Bluetooth was working (or, at least, connecting), but I could never get the Serial commuincation to work afterwards .. well, I could send to the Android, but I couldn't receive from the Android. And I knew the Android was sending because if I held down the reset button on the Arduino (so the sketch that opened the Serial port wasn't running) I would get the data from the Android in the Arduino Serial Monitor (or garbage if the baud rate was wrong) .. so, I was definitely receiving! But opening the serial port in the Sketch (with the Serial.begin() call) seemed to be causing me grief .. and the MeetAndroid library required that I did it .. so .. Catch 22 (if I called the Serial.begin() I couldn't receive data, but if I didn't I could, but I had to 'cause Amarino understandably requires it to be open) .
Anyhow .. then I found that if I wrote a little Arduino sketch that opened both the normal Serial Port and a Software Serial port, and moving the wires that ran between the TX/RX on the Arduino and Bluetooth to the pins specified in the Software Serial initialization that I could get the data coming from the Android no problem.
So, I decided to play around and change the Amarino MeetAndroid library so that it used a Software Serial port rather than a Hardware Serial port .. make some minor changes to a couple Amarino sample sketches and voila .. it worked!
I have added a link where you can download a SoftwareSerial library-based version of the Amarino MeetAndroid library and I've also included the modified sample sketches.
So, for example .. for the Amarino Test application:
The first few lines look like this (past the comments):
The SoftwareSerial version now looks like this:
In addition, you need to remove the Serial.begin() call from the setup() function (the Software Serial port is intialized in the MeetAndroidSS class initialization and NOT with the Serial.begin() call .. in-fact if you leave in the Serial.begin() .. it probably won't work .. especially if you keep the RX and TX pin numbers at 1 and 0 respectively.
Oh .. and I did add a meetAndroid.send() call in the Test sketch testEvent() function so that I could see an 'Arduino Says' message in the Amarino Monitor.
I have changed the class / directory name so you can have both the SoftwareSerial-based and HardwareSerial-based libraries installed at the same time.
And remember .. the Baud Rate on your Bluetooth module has to still be the same as the Baud Rate specified in the class initialization call. I've found the highest I can use without any problems is 57600 .. I'd recommend starting low at 9600 baud and working you way up to 115200 baud to see if/when it stops working.
Also, remember, if you are using a Mega or Mega 2560, there are limitations on which pins can be successfully used with the SoftwareSerial library .. 1 and 0 aren't included in those pins .. I personally just change the 1 and 0 to 51 and 50 (and connect wires appropriately).. that way all I have to do is remember that I need to add a 5 before both the RX and TX pin numbers if I'm using my Mega 2560 rather than my Uno (note: 11 and 10 are also available similarly as usable with the SoftwareSerial

library for the Mega and Mega 2560, but the MultiColorLampTutorial sample uses both of these pins for LED output, so be careful) .. here's an example using 51 and 50:The MeetAndroidSS Library and all modified Amarino examples can be found here.
If you are working with the samples from the Arduino + Android Projects for the Evil Genius book (by Simon Monk).
The changes are as follows for the ch01_droid_droid sketch:
1. Add an #include <SoftwareSerial.h>
Softwareserial.h Library Download
as the first line of the sketch.Softwareserial Arduino Library Download
2. Change the #include <MeetAndroid.h> to #include <MeetAndroidSS.h>
3. Change MeetAndroid phone; to MeetAndroidSS phone(baudRate, 1, 0);
or whatever pins you use
4. Delete the Serial.begin(baudRate); line in the setup() function.
5. And don't forget that you may need to change the baudRate value to something other than 9600.
