Server Auth Type Select the encryption algorithm scheme used by the OMA-DM server to
communicate with client devices. If the scheme selected here does not match
the actual scheme used by the server, then server will challenge the BM2022w to
automatically update its settings.
• None - No authentication.
• Basic - Server ID and Password are encoded using a Basic Access
Authentication Code.
• Digest (MD5) - Server ID and Password are encoded using a Digest Access
Authentication Code.
• HMAC - Server ID and Password are encoded using a keyed Hash Message
Authentication Code.
Server ID
Enter the identification code for the server. This is used by the BM2022w during
the communication handshake process to identify the server.
Server Password
Enter the password for the server’s identification code. This shared public key is
used by the BM2022w during the communication handshake process to identify
the server.
Server Nonce
The BM2022w and the OMA-DM server use nonces to authenticate each other if
you select MD5 as the authentication algorithm in the Server Auth Type field.
Nonce is an abbreviation of 'number used once'. It is normally a random or
pseudo-random number applied in an authentication protocol to protect existing
communications from being reused in ‘replay attacks’.
Type up to 20 digits for the OMA-DM server nonce.
Client Auth Type
Select the encryption algorithm scheme used by the OMA-DM server to
communicate with client devices. If the scheme selected here does not match
the actual scheme used by the server, then server will challenge the BM2022w to
automatically update its settings.
• None - No authentication.
• Basic - Server ID and Password are encoded using a Basic Access
Authentication Code.
• Digest (MD5) - Server ID and Password are encoded using a Digest Access
Authentication Code.
• HMAC - Server ID and Password are encoded using a keyed Hash Message
Authentication Code.
Note: Make sure that the scheme selected here matches the Server Auth Type.
Client ID Enter the client name for the BM2022w.
Client Password
Enter the password for the BM2022w’s client name.
Client Nonce
The BM2022w and the OMA-DM server use nonces to authenticate each other if
you select MD5 as the authentication algorithm in the Client Auth Type field.
Type up to 20 digits for the OMA-DM client nonce.
Periodical Client-
Initiated Enable
Select this to allow the BM2022w to periodically connect to the OMA-DM server
and check for configuration updates.
If you do not enable this feature then the BM2022w can only be updated
automatically when the OM-DM server initiates contact with it and if you selected
the checkbox on this screen.
Periodical Client-
Initiated Interval
Enter the time interval (in seconds) at which the BM2022w connects to the OMA-
DM server.
