How to use Samsung Gear S2 or Gear S3 with devices that have less than 1.5GB of RAM

Issue

When you try to connect your Samsung Gear S2 or Gear S3 smartwatch to a smartphone that has less than 1.5GB of RAM for the first time, you are in for a nasty surprise; although you can find and install Samsung Gear manager application from Google Play store onto your device, it will be unable to successfully connect your smartphone and the Gear S2 / Gear S3.

Samsung Gear manager app can't find and connect to Gear S2 / Gear S3
Samsung Gear manager app can’t find and connect to Gear S2 / Gear S3

If you try to connect Gear S2 / Gear S3 to your device manually, that is directly from phone’s bluetooth settings, the phone is able to find Gear S2 / Gear S3 and even initiates the pairing process together with the “Confirm passkey xxxxxx to pair with Gear S2.” or “Confirm passkey xxxxxx to pair with Gear S3.” message. After you confirm the bluetooth pairing request, a “setting up…” text is displayed on your Gear S2 / Gear S3 watch but the process doesn’t succeed. The connecting process between the smartphone and Gear S2 / Gear S3 needs to be performed from within the Samsung Gear app in order to be successfully completed.

The reason why Samsung Gear app is unable to find and pair the Gear S2 / Gear S3 with devices that have less than 1.5GB of RAM is the Samsung Gear manager app itself; the developers at Samsung enforced a minimum RAM requirement check into the app. When Samsung Gear app is run on the devices that have less than 1.5GB of RAM, it is only able to find and pair with Samsung accessories such as Gear Triathlon S/M, Gear IconX R/L and Gear Circle but not the Gear S2 / Gear S3.

I suspect the reason for their decision is they have encountered some performance issues on some of less capable smartphones during the testing phase and decided to drop support for the mentioned devices altogether to prevent potential complaints from customers.

How to use Samsung Gear Fit 2 with devices that have less than 1.5GB of RAM

Issue

When you try to connect your Samsung Gear Fit 2 sports band to a smartphone that has less than 1.5GB of RAM for the first time, you are in for a nasty surprise; although you can find and install Samsung Gear manager application from Google Play store onto your device, it will be unable to successfully connect your smartphone and the Gear Fit 2.

Why did developers at Samsung impose such a limit is beyond my knowledge, since I am able to successfully connect and use Gear Fit 2 with Sony Xperia T3 smartphone (Android 4.4.4, 1GB RAM) by utilising a modified Samsung Gear app (I have removed the minimum RAM requirement check from the app). I have contacted Samsung on this matter, but up until this moment, I am still waiting for a more technical response, in comparison to the generic one I received, that can be seen below:
“…In order to proper functionality the Gear Fit 2 with all the purpose it was manufactured for, there are some set of requirement standards set for any phone/ Gear watch. For efficient performance the phone needs particular requirements…”

Do-It-Yourself PACE Instant-SetBack Cubby – Simple LED Light Sensor Switch Circuit

Go straight to the procedure

Issue

Some of the work I do, such as soldering components with large thermal mass on multi-layer boards, requires the use of a high-powered, temperature controlled soldering station with fast thermal recovery and lead-free soldering capability. An under-powered 35W soldering station I already own, just isn’t suitable for that type of work. So, I treated myself with a PACE ST-50 80W Digital Soldering Station which came with a composite / cartridge type soldering iron and a standard tool stand. Since the heater element and thermal sensor have been integrated into the soldering iron tip, the thermal transfer is excellent and overshoot is eliminated. The build quality of this station is exceptional.

PACE also offers a smart tool stand that is capable of detecting the presence of the soldering iron. It is called an ISB or Instant-SetBack Cubby (Part #: 6019-0084-P1) and it costs around 100 USD. When the ISB Cubby detects the presence of the TD-100 soldering iron, it waits for 45 seconds and then puts the iron into the temperature Setback mode. Setback Mode means that the temperature is reduced to just below solder melt temperature (176°C/350°F) so the corrosive action of the leaded or Lead-Free solder is stopped, maximizing the life of the tip and minimizing the electricity bill. When the iron is removed from the cubby, the system returns to normal operation within seconds. The mentioned cubby is suitable for ST 30, ST 50, ST 65, ST 70, ST 75, ST 115, WJS 100, MBT 301 & MBT 350 units.

Since ISB Cubby Mini-DIN-3 port has been present on the back side of my unit, I did some research on the soldering iron detection mechanism. I came up with a simple, but reliable do-it-yourself, minimal component and low cost solution. All the information required was provided in this thread on the eevblog.com. I was reluctant to use a simple mechanical switch due to the reliability issues; the iron handle is too light to surely activate the switch every time, moreover switch shorting or burn could occur in the harsh, high-temperature and solder spatter contaminated environment. I couldn’t use an infrared activated switch solution since I didn’t have an IR photo-transistor or an IR LED on hand. However, I could easily find an ordinary white LED diode, a photoresistor (or light-dependent resistor, LDR, or photocell; light-controlled variable resistor), NPN transistor (or bipolar junction transistor, BJT for short), 500K potentiometer (or pot, variable resistor, rheostat) and a Mini-DIN-3 connector cable (a modified Mini-DIN-4, Mini-DIN-7 or S Video Cable can also be used). These are all the parts that are needed for this simple light-activated switch / soldering iron detection circuit.
