Hi,
No, I'm afraid there isn't. Bangle.js 2 has 8MB of flash, and you can use compression on the data you write to make that go a bit further.
However short of unsoldering the flash chip and putting on a bigger one, which is quite a big undertaking, there's no way to extend that.
What data were you wanting to log, and how often?

Thank you Gordon.
I basically want to log IMU with 3 axis, maybe sample rate 10-20.
So I guess I have to store in 4MB flash and transmit to PC when it is full. -

Ok, it seems like if you store the data as Uint16 (which is all you get off the accelerometer) it's 6 bytes per sample and at 20Hz that's 432kB per hour. So on Bangle.js 2 you're still looking at 20-ish hours.

Seems the duration is not bad. I will try it later, thanks Gordon.
After reading the tutorial and some posts, I knew that bangle can collect data offline and transfer it to PC later.
However, the storage space is not large enough if I want to store several hours' data.
And seems that bangle.js doesn't support SD card?
So is there any solution to extend my data storage?
Thanks in advance.
