Nordic nRF51422 is a SoC works for dual BLE and ANT+

However, what the advantage to build up Heart Rate meter & Cadence Meter by Nordic nRF51422 solution?
The best advantage for MDBT40ANT build by nRF51422 is 

"Dual Mode transmission BLE & ANT+ at the same time"

1. Compatible to customer original ANT+ Device
2. Real Time transmission to ANT+ meter & Smart Phone
3. Long Distance (upto 80M) based on Raytac Module
4. Easy to expand to further applications based on BLE profile
5. Easy for training history tracing
6. Easy team management
7. Easy to link to cloud or server

2018/12/1 Information Updated

1.Raytac MDBT40 Series Module (Nordic nRF51 Solution) BT4.2 Certification Granted

2. Bluetooth SIG Announces Deprecation and Withdraw of Legacy Bluetooth Core Spec Version

Raytac Introduces Ultra Compact & Cost Effective Bluetooth® Low Energy Modules Using Nordic Semiconductor nRF51 series Ultra-Low Power System-on-Chip 

Raytac announced that the new cost down version of BLE module MDBT40-P has been released today.
In order to benefit all customers can easy adopt this new module, MDBT40-P are fully compatible and pip to pip design to the original one, MDBT40.

Part No.:
MDBT40-P128: nRF51822 128K
MDBT40-P256: nRF51822 256K
MDBT40ANT-P256: nRF51422 256K

Size: 1 x 1.8 x 2.7 cm (W x L x H)

Thus, all our customer who has built up the products based on MDBT40 does not need to change anything, 
just straightly swift to the MDBT40-P and start to enjoy the cost down effect.
(No need to modify the carrier board, no need to modify the firmware, even no need to apply safety certification again such as DID/FCC/Telec/CE)

The major difference between MDBT40 VS. MDBT40-P is the Antenna.
MDBT40-P changed the antenna component from chip antenna to printed one.With less component needed, Raytac can successfully conducted cost effective benefit to all our customers.
Comes with printed antenna version, the only demerit of MDBT40-P is the transmission distance will become 70M~80M which is around 10M shorter than original MDBT40. 
However, 70~80M transmission distance is already a superior performance over most of customer's specification required.

                             SIze (cm)        Working Distance (Open Space)
MDBT40               1 x 1.8 x 3.1              80~100 M              
MDBT40-P            1 x 1.8 x 2.7               70~80  M 

Raytac never satisfied with our current perfect result of the module performance, but continually study and find the best solution to improve in terms of cost, performance and delivery.We believed this is the best and only way we can contribute to all the customer who trust us.
