We have an existing design based on the DA14583 that uses DSPS as detailed in UM-B-038, UART comms in/out is h/w flow controlled at 115200 baud. Communication is always from DA14583 to a custom android application with the application always initiating connection to the advertising DA14583.
We are now switching to the Inventek DA14585 based module and latest DSPS as detailed in UM-B-088. Initial tests have not been very successful. We have comms in 1 direction (Android application to DA14585 and out of the UART TX) but data into the DA14585 does not seem to be transmitted and the h/w flow control stops.
We have not modified our custom application and want your comments on the following please.
1. Do you expect an existing android application based on UM-B-038 to work seamlessly with the latest DSPS and DA14585 (GPIO allocation adjusted to suit h/w of course)
2. Has w/h flow control sense changed between versions ?
3. Are there any default compile switches that should be disabled to allow compatibility with existing android applications ?
4. Is there any version migration document I have missed?
Any help would be greatly appreciated, the number of compile switches and configurations is significant and we are under time pressure to get this working, something we thought would be a simple compile with GPIO adaptations.
