<cr,lf>ERROR nn<cr,lf>
Description:
This command reads (gets) the value of one of the variable attributes
identified by ‘aaaa’ and sub ID ‘ssss’ in the attribute collections for that
agent identified by the handle ‘hhhh’. For the embedded weigh scale data
specialization this command reads the value of an attribute listed in Table
14-1.
The value always returns as a string of hexadecimal digits representing
the binary value, and the size of that string is even. Different attributes
have different sizes.

Command:
AT+HAL
Response:
<cr,lf>OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
This command must issue after sending at least one AT+HAE command,
and registers and activates the SDP record with information supplied in
the AT+HAE commands.
Without the SDP record, a manager is not able to make a connection to
the HDP agent, although it is rare for a manager to initiate connections in
typical usage scenarios.

Command:
AT+HARhhhh,pppp[,aaaa[,aaaa[…]]]
Response:
<cr,lf> OK<cr,lf>
Or
<cr,lf>ERROR nn<cr,lf>
Description:
This command triggers a scan report for person ID ‘pppp’ (16 bit decimal
number) from the agent identified by handle ‘hhhh’.
If the agent is not associated with the bound manager (see AT+HAB)
then it first triggers the start of an association.
Once association exists, a scan report sends.
If [,aaaa[,aaaa[…]]] is absent from the command, then the standard scan
report as identified by the attribute MDC_ATTR_ATTRIBUTE_VAL_MAP
in the NU collection sends to the manager. Otherwise, the
[,aaaa[,aaaa[…]]] can be a list of any attribute mentioned in the NU
collection. For example, to send a scan report with just the measurement
status, just specify the single value 2375.
Please note that only attributes mentioned in the NU collection are
allowed. Any ‘aaaa’ value not found in the NU collection is silently
ignored.
