sleeplog: Fix LOW_MEMORY,MEMORY error #1835

[storm64]

Check and if neccessary reduce logsize to 1500 entries in writeLog() to prevent low mem error.

Thanks! Just to add that you could use StorageFile (which handles appends) to store one record per line (still as JSON) and that'd mean you could store data much more easily - it'd be way faster and it'd hardly use any memory. The current method is rewriting a whole new file for each entry added too.

You could then 'stream' the data out, line by line, and again there would be no memory limits.

While 1500 would (I think?) work on Bangle.js 2 as long as there isn't much data it'd still kill Bangle.js 1.

The "new" sleeplog is using StorageFiles and only writes old data into a seperate new file.

While 1500 would (I think?) work on Bangle.js 2 as long as there isn't much data it'd still kill Bangle.js 1.

The sleeplog app is not supported on Bangle.js 1 for now because of the excessive memory needed.
I hope the new app might be able to run on lower memory.

Ahh, great - thanks for letting me know!
