nRF51 or nRF52? MTU Packet is the question!
Inevitably, the payoff in term of cost of the the technology improvement is essential.
Nordic has launched various of BLE SoC such as nRF51822, nRF52832, and nRF52840.
Raytac recently has been asked frequently~How we can decide to use nRF51 or nR52?
Which solution is the best adoption for the implement?
Is the best and latest solution always the right option for developers?
Standing on Marketing point of view, a Right solution does not mean the Best and Latest technology.
A Right solution is hard be the assertion but need more connotation of cost structure analysis, strategic product road map planning, initial cost speculation comprehended.
Likewise most of electronic components, developers tents to use a simple way to judge how to pick up the BLE SoC soltuion
1. Unit Cost
There is no doubt that Unit Cost is important if the solution specification is sufficient.
However, if customer leave the future roadmap plan behind and pick up the current cheapest solution, to change an advanced solution to fit the next implement will be the payoff occurred in next product. (The payoff which is refer to the total certification cost)

How we should pick up Nordic solution? nRF51 or nRF52? What is the difference?
What the module we should pick up? MDBT40 series or MDBT42 series?
No doubt that nRF52 has below merit rather than nRF51
