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.
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 🙂
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 would like to announce MDBT50Q series Bluetooth Module which deployed Nordic nRF52840 solution have WPC (India) certificate granted.
We believed it will help Indian customers breakthrough to Bluetooth world with Raytac WPC certified nRF52840 modules.
After Nordic released nRF52840, the confusion raised what the difference between nRF52832. Raytac provided an easy comparison chart based on module solution hopes to provide a quick understanding in between.
With over 3,800 exhibitors gathering in Hong Kong, Global Sources has become one of the largest specialized sourcing trade fair around electronics.
We are excited to announce that Raytac will be in attendance over there to present our latest products:
1. Nordic nRF52840 Solution Module: MDBT50Q Series
2. Nordic nRF52810 Solution AT Command Module
3. Nordic nRF52832 Solution AT Command Module
4. Osram Laser Solution: Ultra Low Power Direct Green Laser Module
5. Bluetooth Application
To know more about Raytac, why not come over to have a chat!
Looking forward to seeing you in Hong Kong!
Raytac’s EE policy (Easy Employee) core is to provide the pre-certified modules.
Benefits from this policy, products built by Raytac’s module may save or reduce the procedure in certification application process which successfully improved Time To Market efficiency and Cost Effective for all customers.
Raytac’s latest module, MDBT50Q series module employed Nordic nRF52840 solution has developed 3 lines with different antenna type.
