Hi,
My target is to create prototype of ANT application with the continuous scan mode. The application works as ANT slave. It is expected to monitor the message boardcast by multiple ANT masters. So in my understanding, i need only enable one channel for continuous scan mode and enable the extended message.
I checked the NRF5 SDK and find the ant_continuous_scanning_controller examples provided in the package can be the starting point.
I do experiment below:
- use the hrm_tx examples provided in the SDK packages continuous sending out message.
- update the continuous_scanning_controller and make it as the receive. The main changes are 1. add the rtt log output. 2. remove the using of response channel. The project is attached.examples.zip
The issue i see is after 128 second, no message can be received.
Here are the environment of my test:
- SDK package. package name is : nRF5_SDK_12.1.0_0d23e2a.zip
- continuous_scanning_controller as ANT slave
- hrm_tx as the ANT master
- IDE: IAR
- Softdevice is S212, version is 2.0.0 with evaluation key.
- Board: a customed board using nRF52832_xxAA
How to reproduce this issue
- unzip the examples.zip attached files
- copy the examples folder to the SDK root folder
- compile and program examples/ant/ant_continuous_scanning_controller_coreboard to any NRF52823 boards
- compile and program examples/ant/ant_plus/ant_hrm/hrm_tx to another NRF52823 board
- open the Jlink RTT client and get the log
Here are the logs i got from the Jlink RTT client:
Time-increase per second[127] ANT Event Received?[1]
Time-increase per second[128] ANT Event Received?[1]
Time-increase per second[129] ANT Event Received?[0]
Time-increase per second[130] ANT Event Received?[0]
Time-increase per second[131] ANT Event Received?[0]
Time-increase per second[132] ANT Event Received?[0]
Time-increase per second[133] ANT Event Received?[0]
When error happens, app_error_fault_handler() will be called and it shows that there is an error reported by the soft device stack. However, i don't get way to debug these issues.
