You can just setup a custom reporting attribute, a uint8_t value that represents the percentage of download made, so the device reports back to the coordinator how much of the download was made.

Yeah its weird, I remember testing it on the stack version 6.5, and worked somewhat ok, now that it is the oficial default scan method, I can't get it to work, but the old method still works, I tried increasing the scan duration expoent to absurdo ammounts, and it still could not see the networks, does it have any incompatibility with simeepromV2?

I give up already as the first sign of instability to me is bad signal and will probably test this again on a later time...

Hello, as I am upgrading SDK of projects and the optimize scans method working like a better way to join networks I am with this problem

Router : SDK 6.7.6 

Parts: efr32mg13p632f512

Gateway SDK : 6.2.2

Default project with absolutely nothing

I cannot join and cannot hear any beacon, and my device cannot join a open network, i left the device for minutes searching, there is zero devices on the gateway, its just an open gateway waiting for this device to join.

So i just uncheck the "optimize scans" option and..

MFG_LIB Enabled 00

Immediately joined the network.

Anyone having problems with optimize scans?

Hello guys today i am trying to experiment NCP-UART-XMODEM updates so my gateway device can update both the z3gateway and ncp firmware via the application so I am trying to compile a bootloader with uart and xmodem but i am getting into this error (that is treated as warning), is it safe to ignore it and carry on or I need to to something?

I am attaching the isc down below too!

This solved my issue.
