Hi, I got myself an H7 Portenta with LoRa Vision Shield. I am closely following the official tutorial on AU915 regional band. However, when I run the program after entering appropriate band=BAND_AU915, appEui and AppKey I get the following error: LoraError: Failed to set autoband Can someone plea…

Hi all, I could finally get this working by switching the frequency plan to AS923 (from AU915) on the Portenta and Gateway (on gateway’s hard settings and its registration on TTN). This is a very Australia-specific problem. I’ve tested several antennas for this and can confirm that the antenna that…

@iabdalkader - Can you help on this?

I don’t know much about Lora, I just ported/implemented the driver to support the custom Arduino Lora firmware. Perhaps try to update/install the Lora firmware from the Arduino IDE ? One thing to test is to see if what you want to do works with Arduino driver/sketch/firmware, if so then it’s likely…

Thanks for the response, Ibrahim! I’ll try using Arduino sketch and get back to you. I intend to use my H7 Portenta Vision Shield for a deep learning project with LoRa. If LoRa does not work on OpenMV, I will have to make a solid decision and move everything to Arduino, which is of course painful g…

Hi, I tried this using Arduino IDE and it worked. I wouldn’t say it’s perfect because sometimes it does not relay data to TTN, but that’s a connection issue I suppose. OpenMV way of doing this still isn’t working. Regards, PC

Can you post the Arduino sketch and the Python script ? Just the function that’s not working.

Hi Ibrahim, The Arduino script is basically the example file ‘LoraSendAndReceive.ino’ with my device’s creds and AU915 band. Here you go: /* Lora Send And Receive This sketch demonstrates how to send and receive data with the MKR WAN 1300/1310 LoRa module. This example code is in the public …

I’m getting a different error now surprisingly. However, here you go! Looking up how to resolve this simultaneously. [image] Regards, PC

You’re getting a timeout error and then it continues to try to send data and then fails as it’s not connected. The example isn’t great, it should raise the exception again after printing the error, to stop the code from going any further.

I edited the code to understand the process better, this is what I get now [image] When I use Arduino and it connects sometimes, it connects quite instantly; I suppose a timeout of 20s is sufficient to connect. Do you know how I can/should further deduce the problem? I first suspected that the i…

Can you post the output you get when running the Python script ?

I don’t get any errors when I run your script, other than the timeout of course.
