I am trying to transmit a large data of 220 characters using LoRa mini dev and while receiving it on LG01 it is displayed 1st time only, and immediately after that, it says connection closed by foreign host, and have to run telnet localhost 6571 again and it runs for 1 time only, and the same problem comes again.

I want to use an external antenna for the LoRa in LoRa mini Dev. What are the steps should I follow in order to do so?

Hi,
I use LT-22222-L with firmware AS923 v1.5.7.
I set the state of RO1, RO2, DO1 and DO2 to ON and all LED indicators are ON.
I find the state of RO1, RO2, DO1 and DO2 loss after reboot (by ATZ) or power off (by unplug the power).
The state of RO1, RO2, DO1 and DO2 is back to OFF instead of keeping ON.

This issue should be already fixed in v1.4.2?

Image v1.4.2

• Update LoRaWAN stack to DR-LWS-003 (http://www.dragino.com/downloads/index.php?dir=LoRa_End_Node/DR-LWS/&file=changelog )
• Fix DO / Relay state lose after reboot. Now After reboot, the DO/Relay will keep the same state as before.

Please help to check v1.5.7 if the issue happened again or there is any temporary workaround.
Thanks a lot.

I'm using a LT-33222-L with TTN and OTAA.

Uplink is running fine out of the box.
Downlink didn't work until I manually set the data rate on the device to SF9/125 using "AT+RX2DR=3".
The device reported "AT+RX2DR=0" before the change.

Shouldn't this be done with the OTAA process?

In order to use timing information from GPS to NTP it is required to take the PPS into a GPIO pin on the Pi, am I reading the schematics correctly that this PPS pin is only wired to the external pin on the HAT?

I have download the schematics for the LGT-92 and see that you are using the MPU 9250 acceletometer , but it is marked as EOL by the manufacturer [1]. Do you have an recommended alternative to this component?

Is it neccesary to have a 9-axis accelerometer?

Thanks in advance!

Hi there!
Just unpack the tracker - looks great! Is the HW V1.6.0 schematic with STM32L072/L76K still open source ? Will it be available from this repo?
Regards!

Does anyone have plans to load the details of the 1.4 version of the LoRa Shield?

For a more universal use, it would be great to have options allowing the controller to send the actual input values on a input change.

Possible use-case

• connecting it to a alarm output
• monitor analog values and alert o bigger changes

Options could be

• on digital input change only
• on analog input change only
• on digital or analog changes
• analog input, required value change in % to trigger

Having read a user who had to add "a cable to feed 5V to the centre pin of the external GPS antenna connector to use an active antenna" I just wanted to check if the external GPS antenna socket is supposed to be powered?

Hi there,
I am unable to compile the code and getting below error.

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Arduino/Genuino Uno"
draginoLora:18:18: error: lmic.h: No such file or directory
compilation terminated.
exit status 1
lmic.h: No such file or directory
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I have placed libraries folder as well all the libraries in the same directory as .ino file. Still program does not verify the code and does not compile as it can't find the said files. Any idea whats going wrong here ? Thanks

Dear Dragino developer,
we are very interesting in your project and we are testing LoRaWAN Dragino.
We have a Lora App Server and Network server online and some gateways based on Raspberry Pi3 and a Concentrator (this one: https://wireless-solutions.de/products/radiomodules/ic880a.html) with the lora_pkt_fwd and lora-brige installed.
For the sensor node we use an Arduino UNO with a Dragino GPS/Shield (with LMIC library for LoRaWAN stack https://github.com/matthijskooijman/arduino-lmic) and this code to send data: https://github.com/dragino/Lora/blob/master/Lora%20Shield/Examples/lora_shield_ttn/lora_shield_ttn.ino

It works both in ABP and OTAA, we receive the data on the LoRa App Server sent by the Dragino node.

We are able to change spreading factor from 7 to 12 in ABP mode and not in OTA. May be with OTA is not possible to change spreading factor on the Dragino code given that is the network server that has pre-configured values? did you do some test with OTA and different spreading factor values?

Can I ask you moreover if you have an idea how to change the codeRate? (now is 4/5) Is it possible to change codeRate on the Arduino/Dragino code?

Thanks a lot
Andrea

see details at manuelbl/ttn-esp32#23

the RST pin on the LoRa shield is missing a pull-up, so the chip is not working if RST pin stops driving.

Hi,
the schematics state that the Lora Mini is running with a 16Mhz crystal and the module is powered by 3.3V. The datasheet of the Atmega328p states under speed grades that for 16Mhz a minimum of 4.5V are needed. While it still might work it seems out of the specified range and might not work under e.g. different temperature/pressure conditions. Isn't it?

it compiles, but it get a runtime error calling os_init() reffering to radio.c
_#ifdef CFG_sx1276_radio
ASSERT(v == 0x12 );

elif CFG_sx1272_radio

ASSERT(v == 0x22);_

it seem that the library is not compatible with the RFM96 used on the board
CLOSED : RFM96 is for 433MHz. wrong board delivered
