Calling this code to fetch a local file from a python temporary webserver (file download tested with chrome and firefox). Results in the following log:

Why do I get "SL_DEVICE_EVENT_FATAL_SYNC_LOSS" ?

Hi,

The sync loss event will get triggered whenever there is an unexpected data on the host interface (SPI between host and NWP). It can be caused by

You code seems ok (it is not trivial to find the issue), but the functions you call are internal and are supposed to be called within the library context. Please use the "ota" reference code to debug such issue if you prefer to take this approach.

One thing i noticed, is that the first call to RecvAppend return with 1440 bytes, that are not processed in the first call to OtaArchive_Process() and immediately you call RecvAppend again (from offset 0). This may cause the issue and anyway is wrong as you overrides the otaBuffer, before its original content was processed.

In such case you should call OtaArchive_Process() twice (or more) until the entire content (1440B) is processed, before the next call to RecvAppend.

Check the handling in Ota_run().

Kobi
