5. AMANOTHI OKUSETSHENZISWA
· ✅ Yakhelwe ukuhlanganiswa ezinhlelweni zokusakaza eziphuthumayo ezihlakaniphile, isekela ukusebenza kude nge-4G cloud platform (isibonelo, "Emergency Broadcast Cloud" noma i-MQTT/HTTP API yangokwezifiso).
· ✅ Isekela ukuphambanisa okubalulekile: okokufaka kwe-microphone > okokufaka komugqa > ukudlala kwe-MP3 (uma isidlali sangaphandle sixhunyiwe).
· ✅ Isivinini sabalandeli siyazilungisa ngokuzenzakalelayo ngokusekelwe ezingeni lokushisa langaphakathi — ukusebenza okuthule ngaphansi komthwalo ongaphansi.
· ⚠️ Ungasebenzi ngaphandle kokubeka ugesi kahle. Sebenzisa isishintshi sikagesi esizinikezele (okungenani 16 A).
· ⚠️ Imoduli ye-4G idinga ikhadi le-SIM elisebenzayo eline-data plan kanye nokucushwa kwe-APN okulungile.
