Sensor output in jack and not in Bluetooth

Hello,
I do not have a connected apartment bike. However, my apartment bike has speed sensors but these are connected to the screen of my bike with a cable with a jack output. I would like to know if there is a solution to connect the sensors of my bike to the application. Would a jack to Bluetooth adapter suffice? Is the application capable of detecting a jack to Bluetooth adapter? Thank you in advance for your answer
