4.1.2. GNSS function¶

There are two types of EC20 modules, one is has GNSS and another is no GNSS. EC20 4G modules sold on firefly’s official website do not support GNSS, and the suffix is SNNS. EC20 modules that support GNSS generally have the suffix SGNS.The public firmware supports GNSS function, but it is turned off by default. For the use method, please refer to the chapter EC20 GNSS function.
