Welcome to return code hell :). The status=8 is actually a Bluetooth
error code, not a NimBLE host error code. In this case, the controller
belonging to the destination device has indicated a disconnect reason of
8, which translates to "supervision timeout." In other words, your PC's
controller unexpectedly went silent, so the NimBLE device was forced to
drop the connection.
The GATT library (what newtmgr uses for BLE) is a bit sketchy, so it's
hard to tell who as at fault. What controller are you using to send the
newtmgr command (e.g., built-in Bluetooth radio)?
Do you have any luck with a smaller newtmgr command (e.g., echo)? The
image upload command is especially troublesome because it causes the
destination device to perform a flash erase operation. This causes the
MCU to stall, which can lead to supervision timeouts. I believe the
newtmgr tool uses fairly lenient connection settings for this reason,
but this could still be the problem, especially on the nRF51.
You could try connecting to the NimBLE device with a known good setup
such as the Lightblue app on OS X or an iphone. Then, subscribe to the
newtmgr characteristic and try writing a value to the same
characteristic. If the connection stays up and you get a notification
from the NimBLE device (newtmgr response), then I would suspect
something on the PC side.
