3.6 Multiple SPPLE Connections Guide

Two SPPLE Connections

  1. In This version, we test two simultaneous SPPLE connections to the MSP430. The remote devices are used as a peripheral device while the MSP430 acts as the central device.
  2. Connect to the first device, discover and configure services on the first device. When discovering services and configuring services we have to specify the remote BD_ADDR that weconnected to.
  3. Similarly, Connect to the second device, discover and configure services on the second device.

  4. To send data to the first remote device data we use LeSend <BD-ADDR> <Number of Bytes to be sent>.

  5. To send data to the second remote device data we use LeSend <BD-ADDR> <Number of Bytes to be sent>.

  6. To read data from the first remote device data we use LeRead <BD-ADDR>.

  7. To read data from the second remote device data we use LeRead <BD-ADDR>.

  8. When the Automaticreadmode, DisplayRawmodedata or Loopback turns on, both connections turn on.

One SPP and One SPPLE Connection

  1. In this version, test an SPP connection and SPPLE Connection at the same time to the MSP430. One of the remote devices is used as a peripheral LE device while the remote deviceas SPP Client.
  2. Connect to the first device, discover and configure services on the first device. When discovering services and configuring services we have to specify the remote BD_ADDR that weconnected to.
  3. Open an SPP server and let the second remote device connect.
  4. To send data to the first remote device data we use LeSend <BD-ADDR> <Number of Bytes to be sent>.
  5. To send data to the second remote data we use CBSend <Number of Bytes to be sent> <Serial Port ID> . If we want to write a small amount of data we use the command Write <Serial Port ID>.
  6. To read data from the first remote device data we use LeRead <BD-ADDR>.
  7. To read data from the second remote device data we use Read.
  8. Turn on Automaticreadmode, DisplayRawmodedata or Loopback (turns on for both connections.)
