LINE introduced an IoT platform “LINE Things” allows Bluetooth Low Energy (BLE) devices integrated to LINE’s ecosystem through LINE Things and operate by LINE’s own developed LINE Front-end Framework (LIFF) application.
Raytac is glad to announce that we has expanded our distributor network to Turkey and Egypt. The distribution agreement with Özdisan Elektronik A.Ş. covers FAE, Engineering, Sales, Marketing and support for Raytac Corporation’s full range of module lines, including nRF52840, nRF52811, nR52832 and nRF51 series in territory.
We encourage readers to visit Raytac’s website to obtain the detail information
Raytac AT command is built based on Nordic UART service, aka NUS, which is similar to SPP (Serial Port Profile) applied in Classic Bluetooth (BT2 and BT3)
To service the Bluetooth bridging works, AT command modules or dongle comes with both Central/Master & Peripheral/ Slave role available.
Latest released MDBT50Q-RX-ATM is a USB dongle designated to connect to PC or Machine acted as the Central / Mater role supporting below commands.
List of supported commands
Raytac today announced (Central / Master) AT command dongle released.
nRF52840 is Nordic’s latest and advanced solution, which brings a new interface “USB” from other lines, has drawn the attention among developers.
Raytac developed AT Command (Master / Central ) solution based on nRF52840 solution, fulfilled the demand of USB interface, missioned to deliver a full coverage of AT Command product line.
Raytac’s nRF52840 USB AT Command dongle, MDBT50Q-RX-ATM is a BT5, FCC/IC/CE/Telec/KC/SRRC/NCC/RCM/WPC pre-certified dongle which is eliminating the need for RF design expertise, and speeding time to market for complex M2M IoT applications.
AT command module is an easy solution provides developers a quick breakthrough to Bluetooth connection. Without firmware effort needed, simply have commands setting on MCU and the start to enjoy the implement of bridging connectivity between devices through Bluetooth.
After Raytac’s completed both Central (Master) & Peripheral (Salve) role AT command module projects, the USB interface has brought up the strongest demand by developers.
Further down in the specification sheet, in section 9, you will find pictures illustrating where exactly on the PCB you can find these pins:
Now we know what to look for and where they are, so now we have only got to tell you how to use them.
Some people might not know this, but for developing these things, you need to get something called J-Link to connect your MDBT50Q-RX to your desktop. However, since this J-Link, when buying the official one from SEGGER, is very expensive, we strongly recommend you to just buy the nRF52840-DK from Nordic Semiconductor as it can be used as a J-Link through their software development kit (SDK) called nRFgo Studio and is MUCH CHEAPER than the official J-Link from SEGGER is.
Sidenote: There are a couple of other reasons why you should just get your hands on a nRF52840-DK from Nordic Semiconductor instead of getting a SEGGER J-Link, but that’s not the topic of this post 😉
When this is done, this is finally how you connect your MDBT50Q-RX to your J-Link to make it all work:
Here you will have to pay attention to the fact that you have to connect J-Link pins 3, 5 & 9 to GND. Otherwise, you won’t be able to burn anything onto your dear MDBT50Q-RX.
The physical connection should look like this:
Pay attention to the direction of the cable, because that will also matter. The direction we mean in this case is which way the slim strip of red is facing.
As we have just revised our MDBT50Q-RX, our customers who have been developing firmware for our USB dongle should take a look at our previous blog post in which we explain about the changes made or contact us directly at firstname.lastname@example.org
Have a good day and we at Raytac wish you smooth and happy tinkering 🙂
To enable hardware reset function in Raytac’s nRF52840 dongle (P/N: MDBT50Q-RX), Raytac’s has revised the circuit and issued the PCN accordingly.
Description of the Change:
1. Change circuit design to enable the hardware reset function.
2. Change PCB Imprint
3. Change Label
4. Change Part No.
Here provided the content of the PCN for customer’s reference.
With over 600 exhibitors gathering in Tokyo, Japan from April 10-12, IT Week has become one of the biggest exhibitions within the IoT Technology sector.
Raytac is pleased to be attending this years IT Week 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 make its second public appearance which powers up the most advanced IoT and Mesh network implementations.
Raytac’s BT5 certified nRF52840 USB dongle, MDBT50Q-RX, eliminating the need for RF design expertise, and speeding time to market for complex M2M IoT applications. The Dongle built by Raytac’s MDBT50Q-P1M module with FCC/IC/CE/Telec/KC/SRRC/NCC/RCM/WPC certification.
To enhance the accessibility to Raytac BLE module sample for evaluation and development, Raytac has put effort to corporate with several channels.
Differ channels may carry various items, we encourage developers firstly visiting Raytac official site. The easy link options listed in each product may help customers to select the friendly channel to approach.
