Using DSPS device app and code, does the module wakes up automatically when incoming data arrives? Does the device asks for permission to send data via RS232? Is there an application note describing the behavior in more detail?
I can send date from a controller to the BL module and see this data also within the DSPS app but I am not able to send data from the DSPS app to the device. I double checked all the connection and they seem functional.
