sendATCommand не объявлен в этой области
Это программа Arduino для GSM и GPS модема. В этом модеме GPS отправляет местоположение пользователю с помощью модема GSM, но постоянно получает эту ошибку.
здесь программа, которую я получаю это снова и снова, даже после того, как некоторые изменения в программе ATCommand предназначены для ответа модуля SIM908 int8_t;

Если вы двигаете функцию
int8_t sendATcommand(char* ATcommand, char* expected_answer, unsigned int timeout)
перед первым использованием (перед функцией setup()) он должен работать.
