The received signal strength interface (RSSI) was measured and used to calculate the Euclidean distance. This method offers a better trade-off between cost, power, and accuracy.Nearby API and a regular beacon simulator application were used as beacons. It is a proof-of-concept study that BLE and WLAN, using readily-available services such as Nearby Application Programming Interface (API) and beacon simulators, can be used for indoor positioning.

In a developing country such as the Philippines, these constraints have more weight and can restrict the advancement of indoor positioning.This study investigates the use of Bluetooth Low Energy (BLE) and Wireless Local Area Network (WLAN) in Euclidean distance computation, which implies prospect use for indoor positioning through trilateration.

How to get Technical Assistance from a Technical Support Moderator.Hobbiest and researchers generally don't need to get the project through FCC complience tests. My understanding is that like the TCP/IP stack you can do whatever you want with it as long as you only use it on Microchip products. That said, I wonder how the XBee modules compare to using a generic RF module and using a freeware zigbee stack like the one that Microchip provides for PIC chips.

That's why source code to operating systems and runtime libraries are available for debugging purposes if you are willing to pay for it. Sometimes just being able to step through code even if you don't want to modify it can assist you in finding bugs in your own code. When you develop something yourself or when you at least have source code that you got from someone else, you can debug it and actually fix it yourself without resorting to gross hacks. Then when you do find out the undocumented limitations you usually don't have many options. Often when these modules don't work, you spend a huge amount of time scratching your head. Sometimes the documentation only tells you 20% of what you need to know. Often bugs and limitations in commerical projects are kept very quite so that a customer doesn't find them until they have made commitments and invested a good amount of resources.

I know this from professional experience. If you want a canned system, go buy one of the many prebuilt or mostly prebuilt robot kits.įrom a professional point of view, building on top of a high level black box module can be more challenging and time consuming then developing things yourself. Sometimes half the joy of working on that stuff is figuring out things for yourself. Maybe this is better.įor this topic, we are talking about building a robot which is clearly a hobbiest project. XBee does have an API interface as an alternative to transparent mode. Sometimes you are sending large amounts of binary data and the extra bandwidth needed and extra processing time to encode and decode the data is too much.

This is closer to what you want for a robot then a serial cable replacement.įirst of all, for some problems a serial line replacement is not the correct answer. I think the XBee would be the next chose since from my glances at the documents it has a packet mode. With something like a robot it's better to have strict timing requirements and have errors( or data loss ) then it is to have retries(Bluetooth SPP ). You can have your own checksums and if the checksums fail just throw out the data untill the next packet. You just periodically send a control packet and receive a telemetry packet as a reply. If all you want to do is sent control information to the robot and receive telemetry information, generic RF modules like the nordic or Linxtechnologies modules are great. You can capture the PWM from the radio controls and have the microcontroller on the robot generate the signals to control the robot based on the captured data. Personally, if you just want to control a robot I would use a RC car controller. One problem is that the timing is very unpredictable, you need to deal with encoding the data to prevent hitting the escape sequence, and performance seems to be very dependent on the bluetooth module and stack on the PC. I've been trying to use bluetooth off and on for a robot project for awhile and I've been alittle frustrated. The modules are expensive and very unrealible. I would personally stay away from bluetooth.
