Hi,
We are using the FIT2 module for one of our customers and I have been asked to update the application with more features.
However, I have run into some serious trouble which is not appearant from any document in the ANT+ sphere. Take a look at the listing below:
• The old code only did four things with the FIT2 module:
1) open the serial port
2) set the pairing distance
3) run script message with the state set to READY
4) listen to the channels 3 and 4 for HRM messages
This worked well. Then I have tried to add a FE master in the code. I obviously must have made some bad choises because if I return to the old code, the HR never appears on either channel. I have tried doing software reset with no change in behaviour. I have been able to find that once the port is opened I get a message saying that I have an INVALID_MESSAGE on channel 4. So the questions from this are:
- Has the module been permanently damaged by my software or has the module stored some bad information in some non volatile memory?
- How can I reset the module to it’s default state (factory reset)?
• There is also some confusion in the documentation:
In the ”ANT FIT2 Fitness Module, Rev1.3” page 6 there is a table which is similar but completely different from the one in ”Fitness Modules Application Note Rev. 3.0” page 11.
- So which is it?
- Is there an ”FE Tx/Rx” supporting channel and what exactly do I need to do to set it up and use it?
- Previously we got HR data on channel 3 and 4 but why don’t we get it now?
- If there are channels that are configured by the module (2-7) what do we need to do with those to make things work?
- What network keys are active by default in the module and on which channels?
