After this happened CHIP_IM_MAX_REPORTS_IN_FLIGHT times (4 by default), we would stop being able to send out any more data reports. This situation is pretty easy to trigger as follows: 1. Use chip-tool to commission a device with node id 17. 2. Start chip-tool interactive mode. 3. Run the following commands in interactive mode: onoff subscribe on-off 0 60 17 1 --keepSubscriptions true onoff subscribe on-off 0 60 17 1 --keepSubscriptions true onoff subscribe on-off 0 60 17 1 --keepSubscriptions true onoff subscribe on-off 0 60 17 1 --keepSubscriptions true onoff subscribe on-off 0 2 17 1 --keepSubscriptions true 4. quit interactive mode (Ctrl-C or quit() command). 5. Wait 60 seconds for all the subscriptions to error out. After this the device will no longer respond with data reports to any read or subscribe requests.
