PDU Coding Rules Currently, text and PDU (Protocol Data Unit) are commonly used for sending short messages. Use text mode to send and receive short message code simple, easy to achieve, but the biggest drawback is not to send and receive Chinese text messages, and PDU mode not only support Chinese text messages, but also send English text messages.

The decoding part was simply completed yesterday, and the encoding part is added today (in the same class ). This method is similar to the encoding part. The attribute is used to decode fields.ProgramWritten in the attribute access section. The decoded function only needs to read these attribute values to complete PDU decoding. The PDU string received by the mobile phone or sms cat contains eight parts:

There are also a lot of materials on the Internet for sending Chinese text messages in the gsm pdu mode. However, after so many days, I wrote my own experience as a record, it is also convenient for other later users to refer. Many materials on the Internet do not talk about the development environment, so I still feel confused in some places. My development environment: Hardware: the GSM module uses the mc52i of Siemens, and the control chip is stm32

There are three methods to send and receive SMS messages: block mode, text mode, and PDU mode. PDU mode is supported by all mobile phones and can use any character set. This is also the default encoding method for mobile phones. Text and PDU (Protocol Data Unit) modes are commonly used to send short messages. Sending and receiving text messages in text mode is si

performer should realize that the lower transmission mode will have an important impact on the interoperability and universality of Internet management capabilities. Select the description of the appropriate SNMP transmission mode in. 2. Detailed Description SNMP usually sets the value of PacketTyepField in the packet type field of the packet header of IPX protocol to 4, that is, PacketExchangePacket ). So

Currently, version 1 is the most widely used SNMP
