Hi Jayant,

It should not take that long. A hypothesis is that it might either be a noisy environment or a lot of retransmissions.

Could you see if you could get an OTA log for both the window covering and the OTA provider?

Kind regards,
Andreas

Hi,

Sorry for late response.

I'm testing with only 1 device from an OTBR docker in my Linux PC.

The actual DFU time is about 1 hour for WindowCovering example.

But it takes only a few minutes from BLE SMP DFU.

Is that normal?

Best regards,

Jayant

Hi,

Just to be clear, what's the speed you're seeing and what are you expecting?

Is there much interference on the network?

How many devices are requesting BDX session simultaneously for an update?

Kind regards,
Andreas
