P2P using NDEP example fails on to DeSelect #272

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Setup two PN532 boards. 
2. On one side, run dep-initiator example.
3. On the other, dep-target example is run.

What is the expected output? What do you see instead?
- Expected Output
  Communication should complete successfully with no errors.

- Actual Output
  Strings are transferred, but the initiator exits with timeout (error code 01) during InDeselect

What version of the product are you using? On what operating system?
1.7.0 Release

Please provide any additional information below.
The chips being used are PN532 chips. One is run from the Raspberry Pi, and the 
other from an Ubuntu 12.04 system using UART.
