Hello Dialog ,
I'm lookink for a solutions for update my DA1484 software .
I'would like to uptdate my BLE Gateway without any connexion , just use the Bluetooth channel for downloading and uptdating the version of my soft.
Can you tell me if it's possible ? My project use a DA14583 as a master to update all BLE device(583).

Hi beblock,
对不起,我不明白这个问题,你will be able to update the fw of a device via the SUOTA profile but that will require to create a connection between the devices. The only way to transfer data via BLE without a connection is via using the advertising string, which is not a reliable solution especially if you would like to transfer a fw.
Thanks MT_dialog
