I’m testing a RAK7243C with LTE gateway. Everything seems to work fine BUT.
Every 24 hours GSM data in ppp0 go back to 4 bytes (4 in and 4 out).
When this issue occurs the gateway appears disconnected in TTN Console.
By killing process using AMA serial port and quickly connecting through minicom or with pppd call gprs everything seems to be fine.
Sim card works great in other gateway brand with same network and settings.
The solution is rebooting. sudo reboot correct the problem. But I can’t stand behind the screen everyday. And I need to setup this gateway without screen or keyboard.
Is it possible to build a reliable gateway with this setup???
I’ve checked the maximum speed of LTE connection through apt-get update max speed is about 10kB/sec. With wired connection it’s closed to the maximum we can reach here.
If your sim card supports 4G and the LTE module supports the frequency band of the sim card, you can refer to the following steps to change::
1.Use command "sudo gateway-config", disalbe lte module, then reboot gateway.
2.Use command minicon connect to the lte module minicom -D /dev/ttyAMA0 -b 115200
3.Input "at+ipr=921600"
4.exit minicom
5.Use command minicon connect to the lte module minicom -D /dev/ttyAMA0 -b 921600
6.Input "at&w"
7.exit mimnicom
8.Use command "sudo gateway-config", Choose "Configure APN name", set the APN name and new baud rate(921600) for pppd
Hello, I tested the lte module for 66 hours, from 15pm on January 15th to now (9am on January 18th).
pppd dial-up is stable and not disconnected.
But lora had several restarts on January 17. Because I use a 2G network, it may be caused by unstable signal quality.
1.Is the GPS of the gateway connected to an antenna and placed it outdoors?
2.Please send me the printed information of "gateway-version".
3.Please send me the printed information of "cat /opt/ttn-gateway/packet_forwarder/lora_pkt_fwd/global_conf.json | grep gps_tty_path".
