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
