@JunJianX It looks like a http server issue. Would you mind providing the OTA URL for us to test.

[JunJianX]

@ustccw Thanks.. https://cnbj2.fds.api.xiaomi.com/ks-firmware-dev/aws8266/01.bin

@JunJianX it looks like work well on my side.

Maybe you could try the following tips:

1. Free heap
   please make sure free heap is more that 10KB+

2. Remove OTA irrelevant code
   please test with examples/system/ota/native_ota/2+MB_flash/new_to_new_no_old for simply issue.

3. Try the latest release version
   release/v3.2 is recommended, commitID is cdcfbee8a488a5e10ef1504d126920ac43fe898d

4. Set 802.11b/g mode for ESP8266 for avoiding router compatibility problems

// ... WiFi initialise
esp_wifi_set_protocol(ESP_IF_WIFI_STA, WIFI_PROTOCAL_11B | WIFI_PROTOCAL_11G);

5. Capture air packets and see what happened
   normally, it is easily for us to see what happened

Hi @JunJianX
I am trying to do OTA update from a remote https server running on my host pc with native_ota example located at examples/system/ota/native_ota/2+MB_flash/new_to_new_no_old. I am able to perform update when the HTTP server and the device are on the same network. But when I try with the device connected on a network different than what the HTTP server is running on , I am getting following errors as :
E (21852) ota: Error: receive data error! errno=104
E (21856) ota: Exiting task due to fatal error...

Looks like you were able to achieve OTA from a remote server. Can you be please share the solution ?

Thanks in advance.

@dipendra77 In the README.md file.

Error "ota_begin error err=0x104"

If you see this error then check that the configured (and actual) flash size is large enough for the partitions in the partition table. The default "two OTA slots" partition table only works with 4MB flash size. To use OTA with smaller flash sizes, create a custom partition table CSV (look in components/partition_table) and configure it in menuconfig.

If changing partition layout, it is usually wise to run "make erase_flash" between steps.

You can find your answer!
