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

2. Specification

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)

Raytac recently has been experienced a frequent question coming up?

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

1. nRF52 supports  Longer Package MTU

2. nRF 52 has over 10 times higher transmission speed than nRF51

3. nRF52 only needs 1/10 (or less) transmission speed  than nRF51

Nordic nRF52832 UART Service Solution (Module: MDBT42Q)

The decisive point for this question we would suggest customer to consider and has a quick review of their current product and future road map in below aspect as below

A. If the product transmission need long packet? (nRF51 packet MTU is 20 byte; but nRF52 packet MTU is over 400 byte)

B. If customer’s future product road map planning may need long packet?

if customer current and all the way to future products may be satisfied by short packet (<20 byte, Thus, nRF51 (MDBT40) is enough.

On the contrast, if current product and future products many need longer packet MORE THAN 20 byte , Raytac is strongly suggesting to consider nRF52 (MDBT42) may be a right option.

Developers who is still confusing about the Right option to pick, Raytac welcome developers to send the mail to us for further consulting.

Anyhow, a right decision at first place is the most important issue rather than changing the solution on the way.

市面上可以選用的藍牙模組甚多, 常有客戶問我們

“為什麼要選用勁達的模組？“

尺寸, 功能表現, 安規費用, 成本

1. 尺寸: 

勁達的藍牙模組是市面上相對較小尺寸的模組模塊, 且模組系列的選擇性多, 可以幫助研發工程人員輕易選用尺寸適合的產品建置在產品當中, 不需要因為受限於模組尺寸的困擾而必須修改產品的外觀設計

2. 功能表現: 

勁達的藍牙模組是以Nordic nRF51及nRF52的方案為基礎, 因此除了是ARM Cotex M0或Ｍ4的MCU, 且內建16K或32K RAM 及256K或512K flash memory 方便研發工程人員可以設計韌體, 運算演算法

此外, OTA (Over The Air)的DFU (Device Firmware Update)的功能更可以方便更新韌體,…

Customers who is familiar with Classic Bluetooth are used to call as SPP service.

Although UART service works with nRF51 (MDBT40 series module) can mostly been satisfied by most implements, customers may be looking for much faster speed and longer package to fulfill widely and various IoT application.

Now, nRF52 SoC (Raytac MDBT42 series module) has brought the solution for those who requests higher speed and longer package transmission applications.

To service all customers and developers, Raytac has strived to build up an advanced open source solution UART firmware corporates with MDBT42 series modules to assist customers obtain the quick way without spending time and energy in developing stage.

nRF52832 UART Service Features:

1. Longer Package MTU

   (500 Bytes for Baudrate 9600 / over 10K for 115200 or 230400)

2. Over 10 times higher transmission speed

3. Less 1/10 shorten the transmission speed

Raytac welcomes all developers who is interested in high speed UART (SPP like) service to contact with us for further more information)
