need transeivers for system development

[T. Rooks]

Hello,

Please be gentle. This is my first time;) .

I am a retired computer/medical electronics/electromechanical device field engineer.

A friend got me interested in developing an idea he had. It involves having various separate units performing precise high speed operations in a time and security critical network.

I have developed several modules and have them working as intended in a 'hard wired' ring topology configuration. What I now need is to get them converted to wireless using as small packages as possible to get no less than 100 meters range in the outdoors. They must also have an operating temperature range of -50 to +85 C. They will spend most of the time waiting for very short transmissions and will respond with very short transmissions.

I am prepared to develop my own protocols for them to sync up and accept commands/data to and from each other as I already have a rudimentary system doing that task. However I would not mind modules that have embedded 16/32 bit processors if I can get documentation and be able to use Basic or C programming and if it can add an extra level of security with minimal time overhead.

Any and all recommendations, suggestions or ideas will be greatly appreciated and acknowledged.

Thanking all in advance for your help,

Tim

Nguyen,

Thank you for the additional info.

I like the idea of having processing power as pat of the Tx/Rcv units. I will have to study the specs for the unit and determine if other factors such as additional I/O and memory will suite my needs. Also Bluetooth is something new to me and I have no clue about how it operates or what it is capable of. Time constraints dictate that I stick with Basic programming if at all possible.

I am having to take some time away from my project to deal with a personal family matter and am not sure how long it will be before I can get back to working on it.

Thanks again,

Tim
