I am not sure whether this is the right thread but I have to start somewhere. I am currently trying to connect to the TTN gateway on the roof of the QUT building, Brisbane, Australia.
The hardware I am using is Arduino-Pro/Pro Mini-based, i.e. ATmega328, 3.3V, 8MHz + Dragino LoRa Bee, 915 MHz, based on HopeRF RFM95W (SX1276).
The Arduino library I am using is the IBM LMIC library to be downloaded with the Arduino library manager:
I am porting it to the Australian regulations as far as I need it to connect the TTN gateway. The frequencies are already adapted. (there is more: TX power, duty cycle, SF, ...). I would like to send data via 125 kHz bandwith channels with SF10 and 30 dB power. (I don't know if my hardware can provide this power). According to the companion "LoRaWAN™ Regional Parameters, v1.0" it is required to use 20(!) channels for frequency hopping when sending with max output power 30 dB.
When I understand your TTN gateway config file correctly you provide 8 RX channels on the gateway:
Just for clarification, am I right when I assume you are using the following channels on the QUT Brisbane TTN gateway:
AU ISM 915
Ch# | direc | f/MHz | BW/kHz | data rate
8 | up | 916.8 | 125 | DR0 - DR3
9 | up | 917.0 | 125 | DR0 - DR3
10 | up | 917.2 | 125 | DR0 - DR3
11 | up | 917.4 | 125 | DR0 - DR3
12 | up | 917.6 | 125 | DR0 - DR3
13 | up | 917.8 | 125 | DR0 - DR3
14 | up | 918.0 | 125 | DR0 - DR3
15 | up | 918.2 | 125 | DR0 - DR3
65 | up | 917.5 | 500 | DR4
0 | down | 923.3 | 500 | DR8 - DR13
1 | down | 923.9 | 500 | DR8 - DR13
2 | down | 924.5 | 500 | DR8 - DR13
3 | down | 925.1 | 500 | DR8 - DR13
4 | down | 925.7 | 500 | DR8 - DR13
5 | down | 926.3 | 500 | DR8 - DR13
6 | down | 926.9 | 500 | DR8 - DR13
7 | down | 927.5 | 500 | DR8 - DR13
Is my assumption correct?
