Come to visit Raytac at Embedded World #Hall 3 / 3-520

With over 1,000 exhibitors gathering in Nuremberg, Germany on 26 Feb.~29 Feb., 2019 , Embedded World has become one of  the biggest trade fair among the IoT Technologies.

Raytac is pleased to be in attendance and present our full range of module family based on Nordic nRF51822, nRF52832 and nRF52840.

Meanwhile, the latest product, MDBT50Q-RX, a multi protocol nRF52840 dongle will first time open to public which power up the most advanced IoT and Mesh network implements.



We welcome all developers come to meet us and look forward to seeing you there.

Bluetooth Project: How to program your firmware to module

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. 


Preparing
1.      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. 

2.    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.

Programing 
SoftDevice + Application
1. Erase all first. Then program Softdevice and follow by Application code.
2. Or you may combine code as stated in above. Erase code and program the combined code.

SoftDevice + Bootloader+ Application
1. Either erase all first. Program the Softdevice and follow by Bootloader. Then use DFU to update the application code.
2. Or suggested having a combined code (SoftDevice+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!

BLE Module Firmware Development Q&A: NFC pins creates “Error 404 – signal not found” (technically)

When you start developing your firmware for your Nordic nRF52832 solution-based Raytac BLE module, you will (like on most other projects) bump into some difficulties.
The other day, we had yet another case where a simple thing caused major difficulties for even some of the brightest people – a customer couldn’t get their GPIO direction bit to work.
Although not too difficult to solve, it’s a common error that most customers end up having on our modules and that is because Pin 0.09 & 0.10 are set to NFC per Nordic’s default settings. In order to be able to use these pins as normal GPIOs, you will have to change those settings.
The two pins I am talking about are the ones linked to the NFC-part to the far left in the circuit example below:
So, to convert these two pins to normal GPIOs, here’s what you need to do:
In SES, you’ll need to add CONFIG_NFCT_PINS_AS_GPIOS.






Pic 1
Right-click on the project and click “Edit Options”
Pic 2
Select “Common”, click on “Preprocessor” under “Code” and then click “CONFIG_NFCT_PINS_AS_GPIOS”

Check out the link below for a reference example on Nordic’s DevZone.
