Can't use multiprocessing on the BLE connections to retrieve data from multipe devices at the same time

I have been trying to get data out from multiple pulse-oximeters at the same time. I was able to run them separately in two different environments and able to extract data from two pulse-oximeters at the same time. I tried to use multiprocessing after the BLE connection to retrieve data parallelly from two pulse-oximeters in the same environment, the connection is getting lost and data is no longer getting received. Then I removed multiprocessing to check whether the code is right and verified that the data is getting retrieved from the code.
How do I retrieve data from multiple BLE devices at the same time using multiprocessing with the library?

The issue names no files, tests, or entry points and includes no reproduction code. Start by reproducing simultaneous BLE connections with and without multiprocessing, then document the supported approach and confirm that data remains available from both pulse-oximeters.
