nrf51822 module

Hi,

i have purchased the following module image description

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

  • I have the similar understanding from all the eBay shops offering these very cheap modules with nRF51822. Btw. why you don't contact the seller or manufacturer? I've seen PIN allocation drawings on eBay as well so they should have some User Guide to these modules answering basic questions like yours...
