Greetings everyone,
I am looking for a piece of info, trying to check on several other forums. Perhaps anyone can advice here. I am trying to upgrade my custom built LoRa gateway from 8 channels to 16.
I have seen couple of similar posts on this forum already, but with no final answer.
I have 2xRAK5146 SPI and RPI. Im using RakWireless forwarder build on Raspbian.
From physical connectivity point, it is clear: I will add second concentrator on another SPI slave, but what about the forwarder service itself?
- Do I need 2 forwarder services, one for each concentrartor?
- How about Gateway ID, can I put identical ID for both?
- Is there any tuning to be done in global_conf.json f.eg? I see there is SPI declaration there, is it accepting array of SPI devices? Like spidev0,0, spidev0.1…
{
"SX130x_conf": {
"com_type": "SPI",
"com_path": "/dev/spidev0.0",
"lorawan_public": true,
"clksrc": 0,
"antenna_gain": 0, /* antenna gain, in dBi */
"full_duplex": false,
"fine_timestamp": {
"enable": false,
"mode": "all_sf" /* high_capacity or all_sf */
},
Appreciate your help
