Pinout changed for Dragino HAT?

[Nanne118]

Hey all, I know this is not within the scope or ''support'' for this, but I cannot seem to get this software / library working with the Dragion GPS/Lora HAT for the Raspberry Pi (3). Although there are a variety of tutorials that describe it as working with this software and hardware combination, the issue I run into is that the pin 4 is not found:

Most likely this is due to the newer version of the GPS/Lora board having a different pinout than the previous versions: anyone here that has also run into this issue and knows how to solve it?

I'm also trying to get this working, but with no luck yet. I think I have a different problem to you, though. I do have files in /sys/class/gpio/gpio4/. Have you enabled SPI in boot/config.txt?

In my case I'm just getting:

FAILURE
radio.c:666

I have got the Lora HAT working with the Radiohead library, using the LORASPI board option, which defines the following pins:

#define RF_LED_PIN RPI_V2_GPIO_P1_16 // Led on GPIO23 so P1 connector pin #16
#define RF_CS_PIN  RPI_V2_GPIO_P1_24 // Slave Select on CE0 so P1 connector pin #24
#define RF_IRQ_PIN RPI_V2_GPIO_P1_22 // IRQ on GPIO25 so P1 connector pin #22
#define RF_RST_PIN RPI_V2_GPIO_P1_15 // IRQ on GPIO22 so P1 connector pin #15

I'm not sure how these CS/IRQ/RST pinouts relate to the lmic_pins.

Has anyone been able to get this to work with the Raspberry Pi 3 B+ (esp. for the US) ? I have it running, but it doesn't show up in the TTN console. I did the following:

1. Change config.h to have: #define CFG_us915 1
2. Change line 764 of lmic.c to LMIC.channelMapp[channel/16] &= ~(1<<(channel&0F));
3. Added in all session keys, eui's and dev address.

Hi,

I’m using a raspberry pi 3b and a Dragino gps/hat v1.4 as a sender. When I run thethingsnetwork code with sudo, I get this error:

Failure
radio.c 664

this does not happen if I launch it normally. It would seem a pin connection problem, could anyone please help me?

Thank you all

you need to check the pin mapping in your lmic code. i had the same error before but as soon as you set the pins properly

// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = 9,
.dio = {2, 6, 7},
};

Anybody solved this? I've changed everything according to the instructions and posts here but no luck, still same radio.c:664
error and no idea how to debug it.

I'm stuck with the same Problem. I changed the mapping like @simortus recommended with one correction of mine: LMIC_UNUSED_PIN changed to UNUSED_PIN

you need to check the pin mapping in your lmic code. i had the same error before but as soon as you set the pins properly

// Pin mapping
const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = 9,
.dio = {2, 6, 7},
};

But the Problem is still:
FAILURE
radio.c:664

Hi @lazarusCantini did you solve this issue? I am having the same problem. Thank you!

[lazarusCantini]

Hey @asanz060 Indeed, I solved THIS Problem. Now I'm struggling with another Problem, but the issue above I solved with the configuration:
// Pin mapping
lmic_pinmap pins = {
.nss = 6,
.rxtx = UNUSED_PIN, // Not connected on RFM92/RFM95
.rst = 0, // Needed on RFM92/RFM95
.dio = {7,4,5}
};
This Configuration works with the Dragino LoRa/GPS HAT for RPi v1.4

Hope this is helpfull!
