nrf51822 module

[sundeep]

Hi,

i have purchased the following module

However, after connecting the VCC and GND to 3.3v DC supply the module is not detected. My questions are :-

1. Does this module come with firmware preloaded, or does one have to load it

2. If the latter, i.e. it has to be loaded - vs using a JTAG or JLINK for some other programmer, can this be done by directly connecting the SWDCLK, SWDIO line to a FTDI or say an Ardunio i.e. use either an FTDI device or an Arduino as a programmer. If yes, could someone please guide me to the appropriate link

3. I also read somewhere, that OTA programming of this module is possible. So will also be curious to understand exactly how ?

regards

Can somebody post all the parts that need to be purchased, with a board like this on ebay. Also what software to use? can I program with Arduino?

Totally agree with @endnode - with anything like this, it's always best to start with the manufacturer's own development/evaluation board. That way, you will get support direct "from the horse's mouth".

Once you have gained sufficient understanding & experience with the manufacturer's own kit, you will then be able to properly evaluate 3rd-party offerings such as seen on places like ebay.
