TC63 AT Command Set

15.2 AT^SRSM

s

<MaxMsgSize>(num)

SAP parameter MaxMsgSize

Handling of this parameter is as follows:

If the TC63 is acting as SAP client the requested value of <MaxMsgSize> is 300. While SAP connection

 

setup this value may be negotiated with the server to the minimal value 274, which is calculated by 256 data

 

bytes as part of a TRANSFER_APDU_RESP message plus a 16 byte SAP header and two status bytes. If

 

the server does not accept this value range no SAP connection will be established.

If the TC63 is acting as SAP server it requires that a <MaxMsgSize> value of 276 will be accepted by a

 

connected client.

<DiscType>(num)

<CmdApdu>(str)
