Good afternoon.
Looking for a solution to the problem in the topics, but never got to the point.
I use Arduino Nano in conjunction with A7 GPRS/GSM/GPS module.
For communication, I use Software Serial on 4 and 5 pin. BaudRate = 9600/
Library: TinyGsmClient, NMEAGPS, BlynkSimpleTinyGSM, SoftwareSerial.
If you run a sketch that does not use Blynk, but simply connects to the A7 module and outputs data to the port monitor with GPS, then everything is beautiful. The data is there, they can be disassembled.
But, wanted to use Blynk for the shell to conveniently transmit GPS coordinates from the A7 module to the Blynk application, such as the Map widget, or just latitude and longitude to virtual variables.
And here there was a problem if in a loop loop blynk,run () works, as I understand, it processes all data from Software Serial itself.
Therefore, I sketch, I do not have to catch separately, which entered the data and checked for NMEA, and then disassemble them.
If you run Blynk.run() on a timer (which of course contradicts the documentation), then the first time the sketch works, I get the data, and they are sent to the widget.
But, after a while, I lose my connection to Blynk.
Tell me, what can be the solution to this issue? You may need some way to track the flow of exchange Blynk in arduino? and from it already take the necessary data, if they are in NMEA format?
The code of the sketch

//======================================================================
// Program: NMEA.ino
//
// Description: This program uses the fix-oriented methods available() and
// read() to handle complete fix structures.
//
// When the last character of the LAST_SENTENCE_IN_INTERVAL (see NMEAGPS_cfg.h)
// is decoded, a completed fix structure becomes available and is returned
// from read(). The new fix is saved the 'fix' structure, and can be used
// anywhere, at any time.
//
// If no messages are enabled in NMEAGPS_cfg.h, or
// no 'gps_fix' members are enabled in GPSfix_cfg.h, no information will be
// parsed, copied or printed.
//
// Prerequisites:
// 1) Your GPS device has been correctly powered.
// Be careful when connecting 3.3V devices.
// 2) Your GPS device is correctly connected to an Arduino serial port.
// See GPSport.h for the default connections.
// 3) You know the default baud rate of your GPS device.
// If 9600 does not work, use NMEAdiagnostic.ino to
// scan for the correct baud rate.
// 4) LAST_SENTENCE_IN_INTERVAL is defined to be the sentence that is
// sent *last* in each update interval (usually once per second).
// The default is NMEAGPS::NMEA_RMC (see NMEAGPS_cfg.h). Other
// programs may need to use the sentence identified by NMEAorder.ino.
// 5) NMEAGPS_RECOGNIZE_ALL is defined in NMEAGPS_cfg.h
//
// 'Serial' is for debug output to the Serial Monitor window.
