Make heltec wireless stick V2 TX only on certain frequencies

#1

Hello, I’d like to make my Wireless stick V2 to transmit data only on certain (in best case 2) frequencies. How can I do that? Is it somehow possible to set using the userChannelsMask? If so what do I set it to if I want only 433 175 000Hz and 433 575 000Hz? (or basically any other 2 frequencies if this is somehow impossible)

Thanks in advance!

This sentence in the example is channel mask.

/*LoraWan channelsmask, default channels 0-7*/ 
uint16_ t userChannelsMask[6]={ 0x00FF,0x0000,0x0000,0x0000,0x0000,0x0000 };

Yes, I know, but I wanted to know how do I set it so the device sends only on two channels if its possible.
