MDBT50Q-DB-40, built by Raytac’s MDBT50Q-1MV2 with Red PCBA deployed nRF52840 SoC with Bluetooth 5 & Thread Combo module Demo Board, equipped Raytac’s MDBT50Q-1MV2 with 1MB Flash Memory and 256KB RAM and Chip Antenna
MDBT50Q-DB-33, build by Raytac’s MDBT50Q-512K with Green PCBA deployed nRF52833 SoC with Bluetooth 5 & Thread Combo module demo board, equipped Raytac’s MDBT50Q-512K with 512KB Flash Memory and 128KB RAM and Chip Antenna
Both demo boards are BT5.1 / BT5 / BT4.2 Bluetooth qualified and FCC, IC, CE, Telec, KC, SRRC, RCM, NCC, WPC pre-certified.
After setup been done, here comes the next question: How to program the firmware in to the module. We are using some simple instruction in below for reader’s quick reference.
Hardware
You will need a Nordic nRF5X DK or a Segger J-link as programmer to load the firmware. To use Nordic nRF5X DK to debug the SoC as well, you will need to order corresponding nRF5X DK to match the SoC number. For example, order nRF52840 DK to debug nRF52840 SoC or order nRF52 DK to debug nRF52832/52810 SoC. But if you are only using it as programmer, any version of nRF5X DK will work as we only use the J-link on this board.
Software
Please download Nordic nRFGo Studio for programming. Remember to install nRF5X Command Line Tools if the board was not detected by nRFGo Studio. Once they are all connected, you can then start programming. Please make sure to “erase all” every time before programming.
For more tutorials and demo of sample code, please visit Nordic’s DevZone and Infocenter where have ample resources to utilize.
Programing
SoftDevice + Application
Erase all first. Then program Softdevice and follow by Application code.
Or you may combine code as stated in above. Erase all and follow by programing the combined code.
SoftDevice + Bootloader+ Application
Either Erase all first. Program the Softdevice and follow by Bootloader. and then use DFU to update the application code.
Or suggested having a combined code (SofDevice+Application+Bootloader) for program. Simply erase all and follow by programming the combined code.
*Remark
Bootloader is needed for DFU (OTA) Function.
SDK 11 (included) and before – a legacy DFU method, which is simple but less security
SDK 12 (Included) and after – a latest DFU method, which has higher security.
To easy customer’s IoT device mass production, Raytac provide code pre-program service into module before shipment. There are requirements listed in below for customers who need the service!
A single, combined hex file is required. Please combine softdevice and application or/and bootloader (depending on your firmware design) together before programming. This will shorten programming time and help to manage your code easier.

Need a simple method to check programming status. The easiest way is to check the device name if device will broadcast device name after programming is done; or use I/O to trigger LED and its behavior. This does not aim to test any or full function of your device, only a simple method for the operator to know programming status.
nRF52840 MDBT50Q Module
Raytac Corporation
A BT4.1 & BT4.2 & BT5 module maker based on Nordic nRF51 & nRF52 solution
nRF52810is an ultra-low power 2.4 GHz wireless system on chip (SoC) integrating the an ARM® Cortex®-M4 CPU with 24K RAM and 192K flash memory, supports BT5.0 (BLE), , the ANT™ protocol, and a range of proprietary 2.4 GHz protocols.
Differ from nRF52832 solution which developed based on S132 Softdevice, Nordic has released S112 for nRF52810 in order to increase the flexibility of application code in limited flash memory size.
Raytac strongly suggest all customer to download the product specification and Softdevice in below link for further nRF52810 development.
Raytac, meanwhile, has released MDBT42Q series module correspondent to nRF52810 solution. MDBT42Q series module is a pin to pin design for both nRF52832 and nRF52810 solution and equipped 2 kinds of antenna, Chip antenna and PCB antenna.
Nordic latest released SoftDevice S132 v5.0 is a Bluetooth 5 protocol stack. It works for nRF52832 and nRF52810 multi-protocol SoCs. The S132 not only supports up to 20 connections, but also offers following 4 Bluetooth low energy roles:
