@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

RE: nRF5 action!
@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 -

RE: nRF5 action!
@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 -
RE: nRF5 action!
@nca78 BTW, HolyIoT makes a similar beacon but nrf52 based. Should be much more energy efficient. The price is about $7

RE: 💬 NModule
Guys, pls. have in mind that Ebyte short NON pa+lna module uses pa+lna pinout.
Took me some time to figure it out -
RE: my first nrf5 ... NRF51/NRF52 which is better for MySensors ?
@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

RE: Why don't you write mysensors library for ESP8266 similar to the nRF one ?
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

RE: nRF5 action!
If anybody need cheap NRF52 DK, Arrow has them for ca. $30 with free courier shipping!

RE: nRF5 action!
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!
-
RE: nRF5 action!
@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? -
RE: nRF5 action!
@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? -
RE: nRF5 action!
@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. -
RE: nRF5 action!
@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. -
RE: nRF5 action!
@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) -
RE: nRF5 action!
@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:

RE: nRF5 action!
@neverdie read Issues section in Mark Cooks's repo referenced above. He's just committed a PR to support the display.
I need nrf52 to able to use Central role in my projects. For Mysensors nrf51 is pretty adequate if someone wants to create something like a wearable weather station
Everything is in place. -
RE: nRF5 action!
@mars-warrior it depends on quantities of both PCBs and components on the PCBs.
If you have lets say 10 pcbs with 20 components and potentially will have to do it again, the best bet is get a small oven (kitchen type) with PID regulator.
If you just need 2-3 pcbs with 5-6 componets, hot air gun is your choice.
In my current project, I solder ebyte module by hand (very easy) and then LED, resisttors and capacitors with hot air and solder paste.
Looks pretty neat. -
RE: nRF5 action!
@neverdie ...and some nifty soldering skills in order to connect to SWDIO/SWDCLK pads

RE: SMD Reflow Oven / PID
@neverdie
two hypothesis:
a) old paste
b) wrong needle gaugeI use Mechanic XG paste, works perfect
-
RE: SMD Reflow Oven / PID
@neverdie yes, although I use the one in small cans and reload small amount into 1 ml syringe (with proper gauge needle!)
This bottle contains all the needles conviniently cut

RE: nRF5 action!
@neverdie I've setup the bootloader for my BT project and I confirm its much easier than it looks.
Can it be used for MySensors? For BT, I create a hex file in Keil and then upload it via nrftoolbox app.
Can the same procedure be used with MySensors? OTA needs Softdevice and Softdevice is not compatible with MySensors -
RE: nRF5 action!
@speechsupply this thread is golden. I was so empowered that was able to easily switch to nRF SDK and to start producing (semi) commercial BLE-ANT device
-
RE: nRF5 action!
@omemanti that's strange, I use the methos regularly and it worls fine.
Oh! Actually, sandeep's installation messes up Jlink drivers so they require reinstall for the method to work.
That's why I am using arduino nrf5 with BMP to completely separate Arduino from Jlink
