Hi Charles,

first thank you very much for creating and sharing your PCB here!

I'd like to use your board (I ordered 8) like a breakout board.
I cant figure out the pin mapping on the left pin column of the LoRasPi 1.2a.
I'd like to connect those pins to an Arduino pro mini.

I made the following pin mapping:

Is the map correct? Could you please correct any errors on LoRasPI col?

I'm using a LoRasPI PCB V1.2a with Single Channel LoRaWAN Gateway installed on a Raspberry Pi 4.
According to your schematic, NSS pin from lora module is connected to CE0 pin on the raspberry, so pin 10 on Wiring Pi.

On global_conf.json, you have for LoRasPi: "pin_nss": 8,
shouldn't be "pin_nss": 10?

Hello, just a quick question, are there any specific details about the smd components needed. What size do the components need to be and what components are needed and what components do I not need (just for sending and recieving messages)?

Thanks,
LouisP

Hi

I just build a LorasPI PCB V1.2a and installed Single Channel LoRaWAN Gateway on a Raspberry Pi 4. I think gateway is running ok, terminal shows

Trying to detect module with NSS=8 DIO0=6 Reset=3 Led1=4
SX1276 detected, starting.
Gateway ID: dc:b6:32:ff:fa:4c:a5:a3
Listening at SF7 on 868.100000 Mhz.
-----------------------------------
stat update: 2021-01-26 12:35:03 GMT no packet received yet
stat update: 2021-01-26 12:35:33 GMT no packet received yet

and i can see it online on TTN dashboard.

The problem is none of the leds light up, at least LED shouldn't be on?
I already checked led polarity or any missing solder/bad components.

Any idea?

Hi Charles,

first of all, great work!

I've managed to construct this gateway and used your version of single packet forwarder, but I'm getting these continuous messages:

On the hardware I soldered the three DIO diodes and I think the rest is OK.

my config is:

pi@raspberrypi:~/single_chan_pkt_fwd $ sudo ./single_chan_pkt_fwd
server: .address = router.eu.staging.thethings.network; .port = 1700; .enable = 1
server: .address = router.eu.thethings.network; .port = 1700; .enable = 0

Can you help?

Thanks a lot!

Hi,

I noticed that there are a split in the board ground plane bellow antenna PCB trace, near of ANT pin of the RF module. Is this OK ? Just another question. Has the antenna PCB trace, 50 ohm impedance ?

Hello ,

I hope this message finds you well. My name is Hirdesh Mewada, and I'm currently working on a LoRa project that involves forwarding packets between LoRa modules. I'm reaching out to the community for guidance and assistance with a specific aspect of my project.

Project Overview:
I'm working on a system where LoRa Module 1 forwards packets. In this setup, when a user is connected to Module 2 (linked to an ESP32 board and acting as an access point), and they enter a URL like "google.com" on their smartphone, I aim to have the request travel from the user's device to the ESP32, then to LoRa Module 2, reaching LoRa Module 1. Module 1 is connected to a Raspberry Pi, which, in turn, is connected to the internet. The Raspi should forward the request to the internet, retrieve the response, and send it back to its connected LoRa Module 1. Finally, Module 1 should forward the response back to Module 2, which can then be accessed by the user on their smartphone. The primary goal is to enable users to view basic text-based HTML websites through this LoRa network.

Specific Assistance Needed:
I'm seeking guidance or examples of code related to the following aspects:

Configuring LoRa communication at 868MHz.
Handling specific LoRa settings for packet forwarding.
Implementing the communication flow from the user device to the Raspi and vice versa.
I understand that your expertise and insights would be invaluable, and I appreciate any guidance or examples you can provide. If there are specific resources, code snippets, or documentation within the LoRa community that could be relevant to my project, I would be grateful for your direction.

Additional Information:

I'm using the pyLoRa library for this project.
and raspi 3b+ ,esp32 ,2 rfm96 modules
Thank you for taking the time to read my query. I look forward to any assistance you can offer.

Best regards,

On the schematics you show three Zener diodes for the OR logic gate between DIO0, DIO1 and DIO2. Must they be Zener or any other type should do? What are the characteristics needed for those diodes? I'm guessing they should be 3216 size from the PCB dimensions.

Thanks

Hi,

Did you test v1.2 please? I have two boards (one with rfm95w and another one with rfm68hcw) and both of them have problems. Transceivers are not detected by spi_scan., On both I connected D0 with 1N4148 and have R3 in place. Anything in particular I should check?

My RPi3 is detecting other boards with rfm95w with no problem.

Thanks
Alex

Do you have a part number for the pin header you are using? I'm having trouble finding a suitable header with staggered pins.
