No practical experience yet, but I have two nrf51 waiting for me to play with. I have been following this thread where I have learned a lot. Seems like a great chip at a nice price.
The Nordic nRF51822 is on the popular micro:bit (http://www.microbit.org/) and a similar project in germany the calliope mini (https://calliope.cc/), so there should be code examples and such to be found.
Sure nordic chips are quite popular, question was rather related to that specific module.
@BoRRoZ I do! I have one for work on my desk right now, and it works great. A client of ours is embedding one on a BLE/IR remote.
You might wait to get a dev kit because you’ll need a SWD probe anyway.
The Nordic SDK is a bit… weird. It’s pretty good, but it gets some getting used to.
How about (I guess fake) Digispark Kickstarter ATTINY85 Arduino IDE compatible boards, no USB-serial converter required for €0.89 each? These are convenient for disposables, garden scares for Halloween maybe? Handy to have like a box of RGB LED’s, you never know when or why one might need these!

I ordered 10 more of these Digispark boards, I am down to my last two. I managed to brick one yesterday flashing a new bootloader. Default has a 5 second pause on boot in case the micronucleus programmer needs to flash a new sketch. Seems the binary I found isn’t the stable version. Windows doesn’t see the hardware now. What a waste of €0.89!!!
Keep up the good work, phenominal amount of info onmthe forum. I have parts ordered for a home made 1/4 wave ground plane antenna. How did testing go? Any other hints?
Thanks

in the category ’ wtf’ is that ? a lorawan gateway pcb with hdmi output … oh, and its not a bargain
LOL… LoRaWAN gateway as a marketing/SEO gimmick.
Maybe it’ll show up in fridges and vacuum cleaners soon.
Isn’t this just what everyone builds here? A RasPi-ish device with a concentrator board on top. Most hobbyist gateway probably have HDMI out that way too .
US $6.29 incl. shipping
nice lan adapter for Pi zero
US $12.34 incl. shipping - I ordered one to see if it can be used
* and suddenly the price went up to US $14.75
