Poll Data (0x0C,0x0D)
| Description |
Poll the device for a message with the specified descriptor set and format. |
|
| Notes |
This function polls for a message using the provided format. The resulting message will maintain the order of descriptors sent in the command and any unrecognized descriptors are ignored. If the format is not provided, the device will attempt to use the stored format (set with the Set Message Format command.) If no format is provided and there is no stored format, the device will respond with a NACK. The reply packet contains an ACK/NACK field. The polled data packet is sent separately as a normal Data packet. |
