how to program

[Claude Bizier]

hello

I am a beginer to design with wireless and I would like to know with soft can be used if i have one master with 4-6 slaves. It seam to be a S120 it right ?.

Also I have a developpement kit nRF51-DK to program nRF51822, is anybody have ever do that. Now I don't need to communicate with mobile just make a local net. the programation is dowloaded via a SPI port and debug feedback with 2 more pins , it is right ?

Thanks

Hi

In the world of Bluetooth Low Energy it is more common to talk about peripherals and centrals. The central device is responsible for establishing the connection, and from that perspective the peripheral can be looked upon as the slave and the central as the master. In your case I assume by master you mean central, and if so, your assumption is correct. The S120 supports up to eight simultaneous Central role connections. Please have a look at the documentation here.

If I understand you correctly you want to use the nRF51 DK to program and debug an external nRF51 chip and this is certainly possible. I don't understan what you try to say in you rlast two sentences, but the nRF51 use Serial Wire Debugger (SWD) and you can see here how to connect the devices. In addition there are lots of threads here on the forum discussing how to program external boards.

Here is a tutorial guiding you through the S120 central example mentioned above.
