In this section we show how to configure a sensor for receiving
firmware updates from an upstream sensor at a determined speed.
This option is suitable for those scenarios where a limited bandwidth
is available, and a normal firmware update procedure would result in
a timeout. For example, one may want to configure a remote collector
constrained by a 50Kbps bandwidth to receive the updates at 24Kbps.
This configuration will prevent the saturation of the communication channel
and thus it will allow to send data traffic while receiving an update.

software_update_slow_mode [true|false] |
|
Description
|
This is a global switch that enables (true) or disables (false) the feature. When
the feature is disabled all the other switches are ignored.

|
Syntax
|
software_update_slow_mode_chunk_size <size_in_bytes> |
|
Description
|
The update bundle is split into multiple fixed-sized chunks. Chunks
are individually transmitted, verified and reassembled. In case of
a failed delivery, only invalid chunks are retransmitted. Essentially,
big chunks are more suitable for high-speed networks, while smaller
chunks are to be preferred for more effective bandwidth limitation.
|
|
Parameters
|
size_in_bytes: the chunk size in bytes. Values are normalized to stay in the range [128, 10485760]. Default value is 4096. |

|
Description
|
Sets the maximum allowed speed for update transfer.
|
|
Parameters
|
speed_in_bps: The maximum allowed speed in bytes per second. Values
lower than 1024 are normalized to 1024. The default value is 4096. Notice that
small chunks add some slight overhead, so generally the transfer speed will remain
consistently below the declared limit. |
