@neverdie for us - yes. For other folks, I think the advantage is the number of targets it supports and the license. Equivalent Segger costs hundreds of $
BTW, Sandeep added BMP support into his core after I raised the issue :-)

else go square

if you ask me, go this way given the BT module itself is already beyond the circular footprint

@alowhum there is a whole "movement" of people who are trying to reprogram them. Key issue is openability (how hard is to open it)
The last easily openable watches are based on nrf51822, but the good thing is that programming pins are easily accesable and even marked SWD/SCLCK.
Search Ali for ID107HR and google for "roger clark smartwatch"
I am yet to find a watch that would be both nrf52 based AND easily openable

Mark is a fantastic guy

@alowhum just buy a real Blue Pill (around $2) and convert it into BMP.
Then you''ll get both a programmer and an USB-serial that you can use to get data from NRF52 UART

@nca78 BTW, HolyIoT makes a similar beacon but nrf52 based. Should be much more energy efficient. The price is about $7

Guys, pls. have in mind that Ebyte short NON pa+lna module uses pa+lna pinout.
Took me some time to figure it out

@rozpruwacz I would strongly encourage you do start with nrf52832 ebyte mosule coupled with Nevrdie's breakout board. It is a) proven b) cheap c) breadboard friendly

Got it, thx. Just to clarify: if I want eg 5 x esp8266 nodes, do I need to add them as 5 gateways, or I add one as a a gateway and other 4 connect to it?

@rozpruwacz said in my first nrf5 ... NRF51/NRF52 which is better for MySensors ?:

So smd modules are no good for me

If so, your only choice is nrf52DK. Solid investment given you get jlink programmer with it

If anybody need cheap NRF52 DK, Arrow has them for ca. $30 with free courier shipping!

What's the proper way to deal with interrupts on nrf?
Many white areas:

• shall I use "smartsleep()" instead of usual arduino way of attaching interrupts? is it enough?
• what pins have hardware interrupts? any?
• what about the macro mentioned in d00016 readme?
• how to overcome nrf51 bug of 1ma power consumption (code-wise)? Otherwise I see no reason buying nrf51 modules if they consume 1ma while sleeping

I thoroughly read al the docs before asking!

@NeverDie wait, d00616 code is basically an extension of Sandeep's. The Sandeep's code (should) supports 8 interupts for nrf52 and 4 - for nrf51.
At least, that's what I conclude from here
Assuming it works, the next question is: can I put just ANY pin into attachinterrupt() function or not?

@NeverDie actually, I am suprised that many of these modules are available and at the prices lower than Ali.
For example:
http://www.fanstel.com/buy/bt832xe
They claim "BT832XE is the longest range Bluetooth 5 module, 1350 meters between 2 BT832XE with used with ANT060 antenna."
$23, shipped within US
Not bad, ah?

@NeverDie Are you talking about MYS or in general? Because, currently there are two completely different approaches to nrf-arduino. One is based on softdevice (or in broader terms, on SDK) while another works direcly with hardware.
For MYS, our only hope is d00616, if he doesn't do it, chances somebody will apapt 52840 to MYS are negligible.
Frankly, MYS don't need it, but that's just my opinion.

@Nca78 Arrow ships free to Russia, but only to companies, not to direct consumers this is linked to the fact they use couriers (DHL/Fedex) and not vanilla USPS.
Have a look at www.shipito.com, it's not the one I am currently using, but Shipito works with the whole world. Pricing might be a bit steep, but I haven't looked at it for a long time.

@nca78 "At first I was afraid, I was petrified" :-), but then I relialized that if "recepting" pads are long enough even plain soldering iron will do.
The solder will just flow under the module provided module pads are pretinned Ias you recommended)

@neverdie thx. Why don't you have a capacitor between DEC4 to GND? I can see only 2 inductors, while Nordic power guidelines prescribe an LC filter between DCC and DEC, ie inductors and a capacitor. nrf52dk also has it.

@gohan said in nRF5 Bluetooth action!:

The ST-Link V2 I found it on digikey and similar sites for around 18/19€, is it the right one?

Don't do that. Either buy $2 clones or invest into DK or:
