Pripojenie k internetu funguje, pripojenie k bluetooth funguje. Zariadenie sa dá programovať cez Arduino Ide, bez akýchkoľvek problémov, avšak mám problém so SIM modulom… Skúšal som pripojenie na internet pomocou sim karty, ale neúspešne… Silu signálu mi ukazuje dobrú, ale pripojiť sa na APN orangu sa mi nepodarilo…
Rád by som vyriešil problém s pripojením, ale inak som s kúpou spokojný.
