11 Send and receive data

NORA-W36 supports several modes for sending and receiving data:
  • String mode
    • All readable ASCII characters (0x21-0x7E, 0xA1-0xFF)
    • Use when sending data in plain text format. For example, when using JSON, HTML, or NMEA.
  • Binary mode
    • All types of characters (0x00-0xFF)
    • Use when all types of data is needed. For example, in binary content using file upload and download.
  • Transparent mode
    • All types of characters (0x00-0xFF)
  • Transparent mode has best performance, due to no wait states
  • Direct mode is faster than Buffered mode
  • Binary mode is faster than String mode
To receive data without an event and read it out, the read mode can be changed to direct mode AT+USORM=1

11.2 Binary mode

The binary mode should be used when binary content is transmitted, like files and binary protocols.
See Binary data for more infomation about the format of the data.

11.3 Transparent mode

Transparent mode (TM) works in the same way as Data mode in legacy products. Note that only one connection of TCP, UDP (Wi-Fi), or SPS (BLE) is allowed.

11.3.1 Transparent mode

To enter Transparent Mode the AT command AT+UTM is used with the option to use TCP, UDP or SPS.
SyntaxAT+UTM=<link_type>,<handle>
Example for SPS: AT+UTM=0,0OKTransparent mode has started+++OKBack in AT mode
Example for TCP socket: AT+UTM=1,0OKTransparent mode has started+++OKBack in AT mode
Until the escape secqence +++ is sent, all data received on the UART will be sent unmodified to the remote device on the specific connection selected.

11.3.2 Transparent mode persistent

Like the Transparent Mode (TM) the Transparent Mode Persistent (TMP) works in the same way as Data Mode in legacy u-blox short range products. Note that only one connection of TCP, UDP (Wi-Fi), or SPS (Bluetooth LE) is allowed in this mode. The only difference with TM and TMP is that TMP can be stored in flash and connect at startup.
To enter TMP, the AT+UTMP command is used - with the option to use TCP, UDP, or SPS.
SyntaxAT+UBTP=<bd_addr>,<connect_sps>AT+UTMP=<link_type>,<config_id>
Example for SPS
