Changing parameters on SAMR34 Xplained for Brazilian LoRaWan.
For anyone who can help me. I'm trying to use SAMR34 Xplained in Brazilian LoRaWAN server, covered by ATC (American Tower). The problem is, they use specific parameters in their Lora network, as use only 8 of 64 channels (from 915.2 Mhz to 916.6 MHz with a 200 kHz bandwidth step for uplink) and more 8 the lasts channels (from 923.3 MHz to 927.3 MHz with a 500 kHz bandwidth step for downlink). And RX1 and RX2 delay of 5s and 6s, respectively.
I don't found any documentation or example explaining how can I select these parameters. It isn't so trivial to discover in the LoRaWAN Mote Application from the example project of SAMR34. Can someone help me with this configuration? Documentations, videos, experiences and examples of SAMR34 in Brazilian ATC LoRa will be very welcome.
I'm using SAMR34 Xplained in AU-915 MHz, activation OTAA with DR4, the keys and I'm inside the ATC LoRaWAN coverage area.
