| - | ===== Configuring the packet forwarder ===== | ||
| - | |||
| - | * Pick the config.json file from the [[resources:resources_spfv2_v3.3.1|resource page]] that fits with your platform, region and feature need. | ||
| - | * Update the JSON configuration file, as explained below. | ||
| - | * The way the program takes configuration files into account is the following: | ||
| - | - if there is a config.json parse it, look for the next file | ||
| - | - if there is a local.json parse it. If some parameters are defined in both config and local configuration files, the local definition overwrites the global config definition. | ||
| - | - in our case the local.conf is automatically generated at boot time. It contains antenna configuration. Do not change this file. | ||
| - | | ||
| - | * In each configuration file, the program looks for a JSON object named: | ||
| - | - "SX1301_array_conf" that should contain the parameters for the Lora concentrator board (RF channels definition, modem parameters, etc) | ||
| - | - "gateway_conf" that should contain the gateway parameters (gateway MAC address, IP address of the server, keep-alive time, etc). | ||
| - | - "gps_conf" | ||
| - | |||
| - | There are many configuration fields among these files, but most of them are by default correctly filled. The configuration you might want to change are the following: | ||
| - | |||
| - | \\ | ||
| - | ==== Radio Frequencies configurations ==== | ||
| - | |||
| - | Each LoRaLoc module contains two SX1301. Each SX1301 can be configured to use 10 different frequencies. However, these channels needs to be contained within a 2 Mhz bandwidth. | ||
| - | |||
| - | * "chip_enable" enable/disable SX1301 | ||
| - | * "chip_center_freq" is used to define the center frequency of the SX1301. All 10 channels will be around this particular frequency (+/- 1Mhz). | ||
| - | * "chan_rx_freq" are used to define each channel frequencies. | ||
| - | * "chip_rf_chain": define the rf chain used by the SX1301. The front-end board integrates two duplicated TX and Rx paths (RF1 path and RF2 path). Each TX/RX path is connected to one SMB antenna port, referenced as RF1 and RF2 (Installation manual 1.5.4.4 Front-end boards). | ||

| - | ==== Antennas configuration ==== | ||
| - | |||
| - | To understand all antennas configuration possibilities read the chapter 4.6.2.4 of the Installation manual. | ||
| - | |||
| - | * “tx_lut”, "rssi_offset", "rssi_offset_coeff_a" and "rssi_offset_coeff_b" fields are used to calibrate the antennas. These values are overwritten by the local.json. No need to change them. | ||
| - | * "rx_enable" and "tx_enable" are used to enable or disable emission and reception of the antennas. In case you only have one antenna, disable both these values for one antenna. | ||
| - | |||
| - | <code> | ||
| - | "rf_chain_conf":[ | ||
| - | { | ||
| - | "rx_enable": true, | ||
| - | "tx_enable": true, | ||
| - | "rssi_offset": -202.5, | ||
| - | "rssi_offset_coeff_a": 20, | ||
| - | "rssi_offset_coeff_b": 2925, | ||

| - | "tx_enable": true, | ||
| - | "rssi_offset": -202.5, | ||
| - | "rssi_offset_coeff_a": 20, | ||
| - | "rssi_offset_coeff_b": 2925, | ||
| - | "tx_lut":[ | ||
| - | { "rf_power": ... | ||
| - | ... | ||
| - | ... }] | ||
| - | }], | ||
| - | </code> | ||
| - | |||
| - | \\ | ||
| - | ==== Gateway Configuration ==== | ||
| - | |||
| - | * “server_address” is the address of the server to which the packets will be forwarded | ||
| - | * “serv_port_up” and “serv_port_down” are the ports used by the packet forwarder to communicate with the LoRa server | ||
| - | * “stat_interval” is the period (in second) at which the statistics of the packet forwarder are logged. | ||
| - | * "forward_crc_valid", "forward_crc_error" and "forward_crc_disabled" are Boolean that defines whether invalids packets should be forwarded to the server or not. | ||
| - | * "keepalive_interval" is the period (in second) at which the packet forwarder will send a PUSH_DATA frame to the server | ||
