add post-write delay and fix debug log formatting

Restore the 100ms delay after BLE writes that was removed in 14f3bd8.
With write-without-response mode, the BLE controller needs time to
transmit the packet before the connection is torn down.

Also fix logDebug calls that used printf-style %s placeholders, which
don't work since logDebug only accepts a single string argument.
