+=== améliorer le decodage: ===
+$PMTK286,1*23
+=== Change unit refresh rate: ===
+<code>
+$PMTK220,100*2F       //Will set the GPS to 10hz (or updates every 100 milliseconds)
+$PMTK220,250*29       //Will set the GPS to 4hz (or updates every 250 milliseconds)
+$PMTK220,1000*1F     //Will set the GPS to 1hz (updates every 1000 milliseconds)
+</code>
+You can set the GPS to any desired refresh rate, you change the value inside the string and generate a new check sum here: http://www.hhhh.org/wiml/proj/nmeaxor.html
+=== To change the baud rates ===
+<code>
+$PMTK251,4800*14
+$PMTK251,9600*17
+$PMTK251,19200*22
+$PMTK251,38400*27
+</code>
+You can also set the GPS to any desired baud rate speed by changing the value inside the string and generate a new checksum here: http://www.hhhh.org/wiml/proj/nmeaxor.html
+=== Enabling the custom binary protocol ===
+<code>$PGCMD,16,0,0,0,0,0*6A</code>
+=== To use NMEA and enable or disable string please refer to this table ===
+|Customize Command Format |   Table 2              |
+|Name           |Example|Units|Description             |
+|Message ID     |$PGCMD |     |Customize command header|
+|Command Number |16     |     |This number represents which command is used|
+|Parameter 1:RMC|1      |     |Period of RMC, 0~5. 0 mean to disable output|
+|Parameter 2:VTG|1      |     |Period of VTG, 0~5. 0 mean to disable output|
+|Parameter 3:GSA|1      |     |Period of GSA, 0~5. 0 mean to disable output|
+|Parameter 4:GSV|1      |     |Period of GSV, 0~5. 0 mean to disable output|
+|Parameter 5:GGA|1      |     |Period of GGA, 0~5. 0 mean to disable output|
+|Checksum       |*6B    |     | |
+|<CR> <LF>|||End of message termination|
+Example that will enable all the messages：
+<code>$PGCMD,16,1,1,1,1,1*6B</code>
+=== Note ===
+When using arduino environment you must add "\r\n" at the end command each line, for example if you want to send the message "$PMTK220,250*29" to the GPS unit, it will be:
+<code>
+Serial.print("$PMTK220,250*29\r\n"); //This is correct
+Serial.print("$PMTK220,250*29"); //INCORRECT!
+</code>
+For deeper information and more command examples please read the official MTK command manual
