ERROR: [main] failed to start the concentrator


(Luisft Silva) #21

SPI is enable and I did not go directly to the local_conf.json i think. when I’m following the tutorial this asks what my Gateway ID, my Gateway Key and the reset pin. And recommends pin 17 for raspberry 3 which is my case, I just put “17” and enter. Can I confirm in any way that I’m using the right pin? For power supply I have one with 5v 1A


(Jac Kersing) #22

For a 3B that is not a lot of power… recommended for RPi3 is to use at least 2A power supply.
For the RPi3 there is also an SPI timing issue which requires changing the boot config, a quick look at the repo does not show anything related to this.
Do you need a Raspian based install? If not I would suggest to use https://github.com/jpmeijers/ttn-resin-gateway-rpi . You could use this on a (spare) sdcard to check the hardware anyway.

hi (sorry for English)
i try semtech packet forwarder with orange pi zero and sx1278(LoRa-RA02)

  1. can i run this gateway ? (in Lora-net say SX1278 supported )
  2. when run packet forwarder ERROR : failed to start the concentrator.?
    • where i can change or set spi pin mosi / miso / sck / reset / Dio0 / CS .( IS necessary )
    • i use wiringOP-zero .
      Thank you for the guide.
      Regards.

(Jac Kersing) #24

You are mixing two projects, sx1278 is a chip for a node. It can be used for a single channel gateway, not for the full gateway software you are trying to run.


(Mvp Iran) #25

Thank you for response.
yes ,but i have only lora-ra02 :kissing_smiling_eyes:.
i run single channel gateway but only supported up link . now i trying to run dual_chan_pkt_fwd.
if you have better suggest , please help me.


(Jac Kersing) #26

Dual_chan_pkt_fwd is the best option. However the error suggests another packet forwarder, not dual_chan_pkt_fwd.

This message is not in the dual_chan_pkt_fwd sources according to github (search). It is part of the source of Lora-net packet_forwarder, poly_pkt_fwd, mp_pkt_fwd etc, software for a full gateway based on sx1301/sx1308.

Hi Jac, I’m trying to build your version of lora_gateway on a Raspberry Pi 3 B+, with the RHF0M301 gateway hat. Is that possible? I’m getting

make all -e -C libloragw
make[1]: Entering directory '/home/pi/kersing/lora_gateway/libloragw'
Makefile:44: *** No SPI physical layer selected, check ../target.cfg file..  Stop.
make[1]: Leaving directory '/home/pi/kersing/lora_gateway/libloragw'
Makefile:10: recipe for target 'all' failed
make: *** [all] Error 2

My library.cfg is the following:

CFG_SPI= native
PLATFORM= imst_rpi 

Is there something I can do to make this work for my hardware? Thanks.


(Jac Kersing) #28

The code should work fine on your hardware. Can you try using the build-pi.sh script included with mp_pkt_fwd?


(Brady Aiello) #29

Hey, thanks for getting back so quick. I ran build-pi.sh , which brough lora_gateway and another copy of packet_forwarder into packet_forwarder/mp_pkt_fwd . Running make in the new lora_gateway directory gives a similar error:

make all -e -C libloragw
make[1]: Entering directory '/home/pi/kersing/packet_forwarder/mp_pkt_fwd/lora_gateway/libloragw'
Makefile:44: *** No SPI physical layer selected, check ../target.cfg file..  Stop.

(Brady Aiello) #30

I needed sudo to build the folders in /opt. Thank you for making this repo. I’ll let you know if I hit any more speedbumps.


(Brady Aiello) #31

@kersing I was able to build it, and now I’m getting the error which is the title of this thread.

(Jac Kersing) #32

The solution is part of the thread as well. Fix the clock setting, make sure the right reset pin is used and allow for a couple of retries. If that all fails use the command line switch to set SPI comms to a lower speed.


(Brady Aiello) #33

Sorry, I couldn’t find any post about changing the clock setting. Where do I set that? I have changed the reset pin to 7, which should be right.


(Jac Kersing) #34

Also, make sure to have SPI enabled :wink: (You wouldn’t be the first to forget that step)


(Brady Aiello) #35

Ah, thank you. Still confused as to what I should set SPI_SPEED to. I saw some info about that here: https://github.com/Lora-net/lora_gateway/issues/26, but none have worked. I’ve experimented with many different SPI_SPEED values in /opt/ttn-gateway/dev/lora_gateway/libloragw/inc/imst_rpi.h, between 50k and 8M, and none have worked. Though now, with SPI_DEBUG enabled, I get some SPI info before the failure:

...

Note: SPI port opened and configured ok
Note: SPI read success
Note: SPI read success
14:24:41  ERROR: [main] failed to start the concentrator

(Jac Kersing) #36

Mp forwarder allows you to specify the SPI speed on the command line (-s ).
Have you locked the clock speed of the RPi3?

What do you use to reset the concentrator?


(Brady Aiello) #37

I’ve tried that method, too. No, I couldn’t figure out how to do that. Overclocking options are disabled on the Pi 3.


(Jac Kersing) #38

Locking the clock requires setting core_freq as mentioned in the message I linked to. Google helps as well…


(Brady Aiello) #39

I read that post feed, but was under the impression you didn’t need to lock it unless going >= 8M on baud. I’ll try locking it anyway.


(Brady Aiello) #40

I set core_freq=250 in /boot/config.txt, rebooted, and tried a range of bauds, but still getting the same error. I’ve tried with sudo ./mp_pkt_fwd -s 8000000. Is that reasonable? With all logging enabled, I get:
