nRF51822 ?

Hi Tom,

You can use the AT commands to configure them as you like I believe. I was lucky enough that the manufacturers site was online yesterday and I got the latest datasheet. Since that site is offline now, I've reposted it on one of my websites http://avalondesigns.nl/dropbox/files/bl­uetooth40_en.pdf

You can have them as central or advertiser and you can set the advertising interval. Is that helpful?

Here is some code I used to set it up:

function switchToMaster() {
  setTimeout(function() {Serial1.print("AT+IMME1");},200);
  setTimeout(function() {Serial1.print("AT+NOTI1");},400);
  setTimeout(function() {Serial1.print("AT+ROLE1");},600);
}

function onInit() {
  Serial1.setup(9600,{rx:A10,tx:A9});
  console.log("Booting...");
  Serial1.on('data', function (data) {console.log(data);});
  setTimeout(function() {Serial1.print("AT+RENEW");},200);
  setTimeout(function() {Serial1.print("AT");},500);
  setTimeout(function() {console.log("Ready!");},600);
}

I have pin 23 on constant 3.3v with the 470k resistor and pin 24 rewired to A14 to use the LED2 of the espruino.

Regards,

Alex
