Hi, I got this very cool board that has a STM32L0 attached to a semtech 1276 in a single package.
first time for me to play with MCU other than Atmel(arduino IDE), so the learning curve is a bit steep. I got myself a ST-Link, installed Atollic IDE.
all the example on the semtech LoraNode github depends on specific hardware platforms(Mote, Motellā¦)ā¦ it gets confusing and not sure where to start just to send a simple hello world to TTN. Iād like a simple example like they use in the LMIC libraryā¦ Iāll learn later how to get sensors data.
Any one has suggestion where to start ? --I already have a gateway(lopy) that canāt wait to receive itās first data !!
I used the github semtech src\apps\LoRaMac\classA\SensorNode
and used fake values for sensors instead of real functions getting sensors dataā¦ like so;
pressure = 10; // in hPa / 10
temperature = 12; // in ĆĀ°C * 100
altitudeBar = 44; // in m * 10
batteryLevel = 33; // 1 (very low) to 254 (fully charged)
//GpsGetLatestGpsPositionBinary( &latitude, &longitude );
altitudeGps = 12;
but I a building the project I get tons of errorsā¦
I not yet to upload the codeā¦ just trying to remove all the extra stuff that complexify itā¦ to start somewhere and understand more clearly whatās happening with the codeā¦
AcSIP so have AT command sets for configuring the Node .But do not have real uses cases available online. it seems, they are working in private with big customers (who buy large number of chips or node from AcSIP)
But Iām now a distributor for their product for North America.
Iām able to supply bare chips, dev boards and help with creating a full solution
( once NDA agreement is signedā¦ )
the chip is very interesting since it has everything included in one 1mm x 1mm SOC
they also have a new model with GPS includedā¦ very low power, c code example in Keil environment (witch is free to use for a STM32F0 ! ) our course for a hobbyist itās not really recommendā¦ will have to deal with impedance traces and antenna placement, power, since itās a chip only offeringā¦ not a stamp module like RFM or other solution so it`s mostly targeted at large customer or project based rather than hobby.
Iām not intimately familiar with this part, but I just went through the same basic process with the module that Iām trying to bring up. The block diagram indicates it has an L073 and an SX1276 in it. Semtech provides support for that combination of devices, so I (perhaps naively) assumed the pinout will need to be modified but other than that I would think it should work.
yea code looks a lot like the original. except a few readily things that help starting quickly with the exact stm32F0 sub model. DIO, I2C, sleeps are all in the example but most other part will be removed ( MOTE sensors things, witch can be complex if only trying to start with the basicsā¦) Iād love to make a few specific dev boards/kits for that chip to get a broader audience but time is missing.
In āmy viewā and Winkie always emphasize on Network effect, where opening the things will motivate users to start may be as hobbyist and evolve to entrepreneur (u never know).
Although it is personal choice of the company to be open or be secretive. But current LoRAWAN IoT industry can succeed only by collaborative efforts .
it is AcSIP choice, do they want to be mass product or niche ā¦technology is moving so fast man.
I think, niche will bring specific customers, less of them but most probably with higher volume and less āmanagementā to each ones. rather get two large ones than thousands that buy 5 units and need 10 hours support each.
having to take care of a forum community, offering really detailed code, clear application notes written to make the hobbyist understand each details is time consuming, costly and does not always payback. IMO.
Results is that Iām happy I can now offer a solid product (and add a local value, maybe cross sells) that is not found on amazon/aliexpress/ebay/Avnet/Digikeyā¦ got a make a living
for example as an added value of someone looking for a chip/dev module, Iāve built a dev kit server/gateway to test lorawan in a mobile fashion, it getās 4G-verizon, rogers, bell, tellus ready(PTCRB certified)/WiFi/LoraWan SX1301, 4x Intel LAN, IP67 compliant(once closed, ha!), on wheels. carry-on sizeā¦ no Rpi here!!
itās an industrial custom made panel frame, 18,5āā Full HD 1920x1080, wide view angle 350nits (1500nits available ) HDMI, VGA, DVI, (( only HDMI is front accessible in this specific case )) and a wide power input 9~36volts DC sealed connector. this one has no touch, it has a anti reflect 4mm tempered glassā¦ really sturdy. but Iām able to make it with either resistive or capacitive touch via USB/RS232 if needed no problem.
the 18,5āā was the biggest size possible in the carry on model. I also do smaller sizes with less optionsā¦ all configurable on needs, and the beauty of it, ā¦ I can make one unit production. no need for a thousand unit.
Iām into industrial embedded PC, for food industry and HMI mostlyā¦ but I always wanted to make suitcase like this myselfā¦ so here is my first one ! many details will be adjusted in the next version but I think itās a good start. Been selling a lot of custom made stainless panel so itās not very hard to just make a custom front panel that matches the selected luggage. I have a model for each Nanuk that has mounting holes in the top cover.
we do drawing to match perfectly the mounting screws and round corners of the caseā¦
