Arduino MKR 1010: Starting LoRa failed! #402

Closed Commifreak closed 3 years ago

Commifreak commented 3 years ago

I read the FAQs and used different libs AND setPins - no luck.

I use an Dragino LoRa shield with an MKR 1010. Should no big deal if the wiring is correct, right?

Dragino PIN Arduino PIN
RST D5
3V3 (PWR LED is on) VCC
GND GND
13 SCK
12 MISO
11 MOSI
10 D4
8 D3
7 D2
6 D1
2 D0

=> https://wiki.dragino.com/index.php?title=File:LoRa_Shield_Pin_Mapping.png => https://content.arduino.cc/assets/Pinout-MKRwifi1010_latest.png

I adapted the pinout from Uno to MKR1010.

I use:

  LoRa.setPins(4, 5, 0);
  if (!LoRa.begin(915E6)) {
    Serial.println("Starting LoRa failed!");
    while (1);
  }

and get The failed message. The SPI wirung should be, right? I dont find the error on the wiring. Any ideas? Thanks in advance!

According to this image, LoRa should connect to D8, 9 and 10. Why you connect SCK to D13? https://content.arduino.cc/assets/Pinout-MKRwifi1010_latest.png

Commifreak commented 3 years ago

SCK is not connected to D13. The PIN labeled 13 on the Dragino is connected to SCK (D9) on the MKR 1010.

So Dragino 11,12,13 is connected to D8-10. Normally they would be connected to UNO's MISO/MOSI/SCK since it is a shield for it.

You may try to use external 3.3v power for your LoRa. And may try to set SS pin to OUTPUT and HIGH before LoRa.begin()

Got it! After trying your tips, nothing worked. Then I tested the Pin lines where they come from and whre they go.

The 3 jumpers (SV2, 3 and 4) were set to ICSP! I had to change them in order to get the data ported to 11, 12, 13. Not the failing did not show up!

Weird - this default setup would never work on an UNO :/

I suggest this to their wiki.

Thanks anyway :)

The picture already mentioned about the pin jumpers.

You miss the basic parts for the junpers!

We can only assume you do the basics right.

I was not sure - this shield is for the UNO - I thought it would be working with default settings, since no text stated this would be important. Sorry about that :(

Nevermind, it works. Happy coding :-)
