I've figured out a way to retrieve a frequency value via netlink: By passing the lora0 ifindex in as attribute, nllora can look up the net_device by index, and then via struct lora_dev_priv call into hooks that the device drivers can optionally implement. :) https://git.kernel.org/pub/scm/linux/kernel/git/afaerber/linux-lora.git/tree/net/lora/netlink.c?h=lora-next Tested with HIMO-01M module. The command might need an additional channel attribute for SX130x. The corresponding nltest program (using libnl-genl) is here: https://github.com/afaerber/lora-modules/blob/master/nltest.c Cheers, Andreas -- SUSE Linux GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Graham Norton HRB 21284 (AG Nürnberg)
