1 month ago Hello, It looks like you're trying to update the same device (AC119ECC-29DC-B020-A2F9-9FC19885A56A) twice simultaneously. I see there are duplicated logs for that device, as if you'd stared it twice, and the device sends "operation not permitted" at some point, when the second instance changes the state for the second time.
For example, you can find the following line twice:
[info] [AC119ECC-29DC-B020-A2F9-9FC19885A56A] DFU Update Log --- Connected to gse-3365108

With iPhone 15, When updating multiple BLE devices simultaneously, we have observed an intermittent
Error 8: Operation not permittedissue. The firmware update zip package has a size of around 360kb. The error usually happens near the start but sometimes happens after several packets are transferred. The DFU secure_bootloader comes from SDK 15.2.0_9412b96 and we do NOT use bonding. We have captured a log with verbosity as below provided.We found a similar issue https://github.com/NordicSemiconductor/IOS-DFU-Library/issues/319 and tried to change packetReceiptNotifications from 1-22 and all values resulted in failures.

Question With this library is it allowed to start multiple devices simultaneously for firmware update? When multiple devices are set to update simultaneously does it impact the message flow, Even though
packetReceiptNotificationsparameter we tried with from 1-20 all resulted intoError 8: Operation not permittederror.Log
