Open GnarFang opened 5 months ago

GnarFang commented 5 months ago

Reproduction steps

The OTA-provider sample can work fine, And using the wifi/Ethernet to transmit data. but the speed of it is sadly slow, I have a 77mb *.ota file, and it made alomst 3 hours how can I resolve this situation, thank you guys very much!!

My platform is Linux platform. OTA Provider and request are running on different Linux platform (Soc i.MX93 or i.MX8MM)

provider

chip-ota-provider-app --discriminator 22 --secured-device-port 5565 --KVS /tmp/chip_kvs_provider --filepath /home/root/thermostat-app.ota &

request

chip-ota-requestor-app --discriminator 18 --secured-device-port 5560 --KVS /tmp/chip_kvs_requestor --periodicQueryTimeout 60 --otaDownloadPath /home/root/download.bin

Even if I add -P 5 to decrease the polling time, but the speed didn't improve. chip-ota-provider-app --discriminator 22 --secured-device-port 5565 --KVS /tmp/chip_kvs_provider --filepath /home/root/thermostat-app.ota -P 5&
