Great Genuine product

Great genuine product, not the fake / alternate XL1278-SMT that other suppliers provide. Great genuine product, not the fake / alternate XL1278-SMT that other suppliers provide.

Wrong product delivered

Wrong product delivered, The advertisement will provide the DRF1278F module but received the XL1278-SMT module, Seller had no intention of replacing or compensate the wrongly delivered modules

Response from DORJI | Nov. 10, 2017

Dear Sir.,

We didn't receive any complaints about the wrong shipments by message or email yet. Could you be kind to tell me if you bought the modules from Tindie? The products here are all originated from DORJI directly. There are a lot of sellers in Ebay or Aliexpress who sell the fake parts. In other words, they advertised the keyword of DRF1278F but the pictures of the products are marked with other part names. I am looking forward to your further opinion soon.

Best regards,
Todd ZHOU

Got > 500 metres range in a slightly hilly urban setting

Wrote some Python code to test the range. At max range settings (BW=125KHz, SF=12, CR=4/5), it takes less than a second to transmit 5 bytes.
One transmitter was placed indoors in my bedroom, and I took a drive with the other plugged into my laptop via the SPI bridge of a SEELablet.
About 500 metres LoS acc to google maps, but the signal had to go through a couple of walls at least. Will test in an open area when time permits.
RSSI at maximum distance was -127

Used the included spring antenna, and set transmit power to 17db. Not sure how to enable 20db, or if it was enabled at all . No significant heating observed, and current consumption is about 60mA .

* This is a P2P LoRA connection . Not to be confused with LoRaWAN. I haven't implemented that protocol, nor do I have access to a gateway here

Awesome Product

If you want a small transceiver buy these because we have been using these in a prototype product soldered to a board with a arduino pro mini and a 3.3v power circuit run using a 18650 battery and have had zero problems. We tested the range and got 2 mile in an urban area through hills and large factorys using a little rubber duck antenna with out any problems , we have not had chance to test the max range yet but i believe we will be able to get much further i have seen people using this chip type to get 200km on high altitude balloons when using a low data rate here is some info http://www.picaxeforum.co.uk/showthread.php?26314-Semtech-s-LoRa-(Long-Range)/page3

so if you want a rock solid transceiver get some of these little bad boys

PS dorji we tried to message you before but got no reply about buying larger quantitys from you we are not looking for discounts just a more direct line of contact and purchasing of up to 100 at a time possibly every 2 - 3 months because we will be using at least 50 a month starting around March so please can you message us with some way of contacting you or should we contact you via http://dorji.com Thanks Mick

All good.

Worked as specified. I have used them on our modular sensing system (called SnapSense).
These are 433Mhz boards and the sample code worked fine. They also worked with the radiohead library

Things to work on:
- The pitch of the pins are really for surface mount -- so quiet hard to hand solder -- especially with shaky hands.
- To make use of full range, you really need a antenna. A simple 50Ohm dipole wire will only give 1-2mile range.

Other than that, excellent and I would/will buy again.
