Ourapplication is a motor control device that is wirelessly controlled from a desktop computer. This is not really what BLE was designed for. BLE is all about low power and is easy to connect to a smartphone. Connecting to a desktop computer however, is much more difficult.
You can use a HID profile. But the latency and data rate may not be what you expect. It is good for a mouse or keyboard. I couldn't get even 20kbits/second with decent latency using the HID examples. Kind of complicated on the PC end I found as well. Maybe you will have better luck. Maybe it will just take a lot of your time.
You may have seen Bluetooth dongles communicating at high speed in windows. Those are probably using SPP which sets up a serial port in windows. The nRF5x does not support this and never will because SPP is not part of the BLE feature set.
A custom GATT profile is theoretically possible but I tried for a month to get some sort of PC software that could communicate with it. Setup on the nRF was easy but every single library I tried on the PC side had some sort of problem. It is like development just stopped about a decade ago. I think everyone went somewhere else. I tried 32feet, lightblue, bluecove, bluetooth SIG and the MS examples. Errors. Out of data documentation. What a mess. Really. I would not wish this on an enemy.
For our application, volume is high so price is a factor. We didn't want the customer to have to use a special dongle. We also needed it work on a wide variety of desktop operating systems. Bandwidth requirements were modest (20kbit/s) and local processing was doable on the nRF but the development on the PC side was just absolutely horrible. What did I end up doing? Went to a Wi-Fi SOC. Longer range. Faster. More CPU. Got it doing more than in less than a day. Easy. It is even cheaper. How is that? Because more people are using this part and that lowers the cost. It does use more power so be aware of that. It is also very easy to develop because people are actually using it an there are zillions of examples. So refreshing to see examples and tools on the desktop that are up to date. No expensive compiler required.
I remember one evening, just wanted to chill and find a new game to get into. Always liked poker and such, so I was searching for something along those lines. Came across -download/ , and it's been quite a find. It's from Pakistan, and they've got all sorts of card games, which I really dig. Plus, the bonuses they throw in are pretty sweet, makes you feel like you're getting more out of it. It's been my go-to app for gaming ever since.
Ironically, Windows 10 CU/FCU might be the fastest BLE platform. Granted, I see 4.5 KByte/sec with my own USB stick, but at work we have BT 4.x USB sticks that can run 12.5KByte/sec against NRF52382 (which reads data from SD card connected via SPI). But I also found out the hard way that I am probably the first "power" user who tried using BTLE with 32-Bit Delphi...
Yeah, BLE on PC is a mess. We work with all 3 platforms at the office. Best is the MAC flawless with builtin BLE support with Corebluetooth. Corebluetooth can also works with older MAC with a dongle. Here is my example code for scanning and read manufacture specific in the advertisement packet.On Linux and Windows, Qt was used with dongle. Other solution for Linux is Bluez. Windows 10 have also builtin driver with Windows 10 only, that works in C#. Examples are available on Microsoft website.
The MS700 was easy to use across my bounty of computing hardware, thanks to the button on the underside that lets you toggle across three paired devices. Multiple Bluetooth profiles are a feature that's becoming more common among wireless keyboards in this price range. The Surface Arc, which came out in 2017, only has one Bluetooth profile, as does Lenovo's Yoga Mouse and Logitech's Signature M650, another smaller, portable mouse that can suit lefties. However, those three comparison mice also have dongles, which makes it easy to keep them connected with two devices.
The MS700 still lets me pair with more devices; however, some prefer the simplicity of a USB dongle. You can also expect less lag with a dongle connection than a Bluetooth one, but I didn't notice any obvious lag while using the MS700 alongside a wireless keyboard, and this isn't the type of mouse you should try to use with a competitive PC gaming setup anyway.
Dell claims the MS700 can last for up to 24 months before needing new AAA batteries. That's four times longer than the Surface Arc's claim (six months), longer than the Yoga Mouse (two months), and equal to Logitech's claim for the M650.
Like many other wireless mice in its price class, the MS700 isn't rechargeable; (although, you could pack it with rechargeable batteries). That's a shame because with USB-C taking over the world, it has become easier to rely on cables to charge peripherals, even when you suddenly run out of juice in the middle of the night while staying in a hotel. But, admittedly, it's still also pretty easy to grab a pair of AAA batteries for the mouse every couple of years.
Dell's MS700 Bluetooth Travel Mouse is extremely portable, but that's pretty much the best thing about it. The scratchy feeling I endured as I moved the mouse around really made it unrealistic for serious, long-term productivity. And matters are only made worse by the hard-to-find touch-scroll strip, which isn't nearly as responsive as a traditional wheel.
There aren't enough perks to elevate the MS700 to much more than a mere 'travel mouse.' Yes, there are more expensive wireless mice, but $65 is pretty steep for something that's best reserved as a backup mouse for when you want to catch up on emails on the go. With more comfortable, programmable, and decently portable mice like Logitech's Signature M650 going for $40, the MS700's debuting MSRP is a hard sell.
After we received the device, we explored it for a few months, and we were stunned with its performance. The way all the components worked along with the system is really a great achievement. Initially we did have problems running it on Linux, which when we switched to Windows, was solved. All the apps like EMOTIV BCI, BrainViz, etc worked perfectly and are giving us great insights about brain activities!
We purchased an EEG EPOC X for our research purposes, as it was the device that could give measurements at the level of detail/accuracy with an amazing price point. The device has been easy to use, but what's really impressive about EMOTIV is the customer service. Every time we had a question, we were able to receive thorough, quick replies. They are also very understanding and accommodating. Thank you for a great experience!
Our laboratory has a good experience when utilizing EPOC X to conduct our research. With mobility, reliable results, and user-friendly software, the device is easy to use and implement research everywhere. The pleasant thing is the impressive quality of the customer service team!! Whenever we had questions, they responded to each of our inquiries quickly and provided satisfactory solutions.
The EPOC system was found to produce very similar N170 ERPs to a research-grade Neuroscan system, and was capable of recording face-sensitivity in the N170, validating its use as research tool in this arena.
Bend-Tech EZ is an entry-level tube bending software for the home hobbyist. If your parts are simple 2D round tube parts only, (parts that lay flat when completed) then EZ will most likely do the trick. A maximum of six bends per part can be done with EZ.
Create a part by starting at one end and then entering in the distance between bends and the angle at each bend. The length values can be apex or tangent values. Custom Part 2D allows bends to reverse direction (180 degree rotation).

From the front, back, top, or either side; it depends on how your shop is set up and what you are cutting. There are multiple ways to easily load material. The tube can be placed in the front gate, then tightened into the self-centering four jaw chuck, and then the front gate can be closed to the correct amount of tightness on the material. Usually, loading takes one person.
The cut speed varies based on a variety of factors; including material size, cut design, material type, tolerance requirements, material thickness, the use of a coolant system, and others. Depending on the variables, the torch can run up to 120 inches per minute while cutting. Between cutting, the rapid travel can run up to 1100 inches per minute (X-axis) and 30 RPM (Y-axis).
The dross level varies based on a variety of factors; including amperage used, cut speed, material size, cut design, material type, tolerance requirements, and material thickness. Optional coolant circulation system can greatly improve the cut quality and dross level. You can request a benchmark/sample package to see the Dragon cut parts in person.
