Over-the-air update aplikasi demo
FreeRTOS menyertakan aplikasi demo yang menunjukkan fungsionalitas perpustakaan over-the-air (OTA). Aplikasi demo OTA terletak difreertos/demos/ota/ota_demo_core_mqtt/ota_demo_core_mqtt.cfreertos/demos/ota/ota_demo_core_http/ota_demo_core_http.c
Aplikasi demo OTA melakukan hal berikut:
-
Menginisialisasi tumpukan jaringan FreeRTOS dan kumpulan buffer MQTT.
-
Membuat tugas untuk melatih perpustakaan OTA menggunakan
vRunOTAUpdateDemo(). -
Menciptakan klien MQTT menggunakan
_establishMqttConnection(). -
Menghubungkan ke brokerAWS IoT MQTT menggunakan
IotMqtt_Connect()dan mendaftarkan callback putuskan MQTT:prvNetworkDisconnectCallback. -
Panggilan
OTA_AgentInit()untuk membuat tugas OTA dan mendaftarkan callback yang akan digunakan saat tugas OTA selesai. -
Menggunakan kembali koneksi MQTT dengan
xOTAConnectionCtx.pvControlClient = _mqttConnection; -
Jika MQTT terputus, aplikasi menangguhkan agen OTA, mencoba menyambung kembali menggunakan penundaan eksponensial dengan jitter, dan kemudian melanjutkan agen OTA.
Sebelum Anda dapat menggunakan pembaruan OTA, selesaikan semua prasyarat diRTOS Over-the-AirUpdate Gratis
Setelah Anda menyelesaikan pengaturan untuk pembaruan OTA, unduh, buat, flash, dan jalankan demo FreeRTOS OTA pada platform yang mendukung fungsionalitas OTA. Petunjuk demo khusus perangkat tersedia untuk perangkat yang memenuhi syarat Freertos berikut:
Setelah Anda membangun, flash, dan menjalankan aplikasi demo OTA pada perangkat Anda, Anda dapat menggunakanAWS IoT konsol atauAWS CLI untuk membuat pekerjaan pembaruan OTA. Setelah Anda membuat pekerjaan pembaruan OTA, sambungkan emulator terminal untuk melihat kemajuan pembaruan OTA. Membuat catatan dari setiap kesalahan yang dihasilkan selama proses.
Pekerjaan pembaruan OTA yang sukses menampilkan output seperti berikut. Beberapa baris dalam contoh ini telah dihapus dari daftar untuk singkatnya.
