RF is a very specialised subject, so you need to consult with an expert in this field, however, its extremely unlikely that you could reach this distance at 2.4GHz without resorting to using very large Antenna's.
Zigbee is a software Protocol typically running at 2.4GHz, not the means of...
When I looked at the video and the chap held the LEDs closer to the camera it looked like LEDs had been modified and the plastic package was longer than it should be for a 5mm LED. Red was picked on purpose since it has the lowest forward volt drop, ~1.8V.
By cutting the LED close to the base...
Ignoring the power supply issue, you need to be aware that GPS in the context of your question is a receiver only device. It can't transmit anything over RF. Satellites in space send out RF signals which GPS 'module' receives and then works out your location on the planet.
In order to transmit...
You could use a GPS receiver module to receive a 1pps signal which is sent out by the obiting satelites referenced to caesium and rubidium atomic clocks. The 1pps out varies from Module to module manufacturer, but there are modules explicitly designed for this purpose (rather than location)...
Yes, the data transmission will take 10's mA for the RX & TX combined plus BLE is limited to about 100kbs of raw data (ignoring the packetisation and error handling in the transmitted stream). BLE connects very quickly to its pairing partner, so you need to think about how much data is going to...
You could try a MEMS Accelerometer which has been used in Pedometers for many years. Since the swimmer is going in one direction you can filter the response to show the peak acceleration on the initial forward stroke which will then die down through the stroke before the swimmer applies a new...
As far as I recall the default settings for the SIM900 is full Modem control (RTS/CTS) signals besides the usual RX/TX. The MSP430 doesnt support full Modem controls, so you need to emulate them with GPIO.
The RX & TX pins operate from 0V to 2.8V, whereas you've indicated that you're powering...
The CC2540/41 doesn't have much space left for user code once the BLE stack is inside the device in terms of user RAM. Also when the 8051 is performing the BLE function there is little or no performance left over for anything else. It might serve you to keep a small MSP430 outside to handle the...
The SIM300 is no longer manufactured by SIMCOM, but instead the upgrade is now the SIM900. The AT commands remain the same, so these commands can stay the same
Their is a paperback book on how to interface a Microchip PIC to the SIM300 written a couple of years ago. The book was called...
Unfortunately the Aptina documents are under NDA. You need to get permission from Aptina to view the documents. Its best to contact a Distributor of Aptina and request the NDA, and your University/College can sign the NDA for the documents.

Hello
I am finding the 1st hurdle difficult to jump with the SIM340 GPRS Module. I have the Evaluation board and I am trying a small exercise to send an SMS message but its failing every time.
Looking at Hyperterminal...I do the following
