Do I have to use external host MCU for nRF51422? What can the ARM Cortex processor inside SoC 51422 do and cannot do?
I want to create a mesh network with hundreds of ANT nodes, each node can scan all nodes in the range of this network and auto pairing (going down the devices list found), and also exchange information (i.e. text) with each other if certain criteria is met.
Is it possible to achieve this with just the SoC nRF51422 without any external MCU (in order to: save power consumption; reduce the complexity of the ANT nodes)? What is the best way to do it?
Another question: if SoC 51422 can work alone to create this application mentioned above, can I add external memory to increase the storage space of each ANT node?
I also plan to use the concurrency of the Bluetooth BLE 4.1 that comes with 51422 for each node, then do I have to use external host MCU for that?
Thanks!
