RE: Best practices for multiple module deployment

If I understand you correctly the two modules you are talking about are software modules that you will run in parallel on the same nRF53 device?

If so I don't see any good way to develop these modules as separate applications with their own hex file, I believe you will have to include them as two separate libraries or source modules in the same project, and compile them together.

All software libraries and examples for the nRF53 are based around the new nRF Connect SDK platform (NCS).

NCS uses the Zephyr RTOS under the hood, which is an open source RTOS optimized for low power IoT applications.

Being an RTOS Zephyr supports multi threading, and provides various OS constructs for handling synchronization between different threads, such as mutexes, semaphores and FIFO's.

For a full overview of the Zephyr OS features, please look at the Zephyr kernel primer.

The simplest way to do this would probably be to just wrap all the BLE calls in a mutex, but with Zephyr you should have several options depending on the application requirements.
