5.3.2 Step 2: Target Detection

It is essential to determine whether the connected device is a CC3100 or CC3200. It is important because additional steps are required for the CC3200. The provided information indicates whether the device is a CC3200 (nonsecured), CC3200S, or CC3200SF (flash device).

The procedure for detecting the target follows:

  1. The main processor sends the Get Version Info command.
  2. The CC3100 or CC3200 device responds with an Ack, followed by the Version Info response. The first byte of the Chip type field must be tested. 
    if (chip type & 0x10)  //the device is CC3200 flavor
else //the device is CC3100 flavor
  3. The main processor responds with an Ack.

Figure 5-3 shows the Get Version Info command and the Version Info response.
