Вопрос ESP8266 - GPS uBlox NEO-6M - не заработал (заработал)

Для кода нужна модифицированная библиотека TinyGPS потому как не компилится функция sqrt() на ESP, бьёт ошибку

../../../../xtensa-lx106-elf/lib\libm.a(lib_a-w_sqrt.o): In function sqrt':

заменено в TinyGPS
delta = sqrt(delta);
на
delta = squareRoot(delta);
и добавлено

float ESPTinyGPS::squareRoot(float num) {

    float sqr = num / 2;
    for (int i = 0; i<15; i++) {
        sqr = (sqr + num / sqr) / 2;
    }

    return sqr;

}

объявлена как

static float squareRoot(float num);

или можно взять в аттаче уже готовую, я обозвал её как ESPTinyGPS

Код общения с GPS - результат никакой (

блин. вроде заработал )))
rx и tx кинуть надо через TTL (5V) - LVTTL (3.3V) конвертер.

Перенесите тогда в скетчи что ли )

У вас запустилось с SoftwareSerial ?
С какой версией?
У меня ругается на avr/interrupt.h
