Just that it should allow the user to create triggers for threshold levels instead of usb-device-paths and have some global configuration parameters -- if we want to over-do it, these could be a Attack(ms), Decay(ms), Sustain (%) and Release(ms)...

I was hoping for something around 50ms so it would feel real-time-ish while adjusting the antenna position(s). But I see how the cost of handling this would add on the rx-path which might not be such a good idea in the end... > For the initial version I was thinking of a simple program that uses > nl80211 directly to poll the signal strength (no need for libiwinfo > abstraction, since I have no intention of supporting non-cfg80211 > drivers with this). It can take a list of LEDs and the signal strength > threshold for each LED from the command line. Implemented in C and linking only against libnl-tiny this could be a very good compromise. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAEBAgAGBQJO7wouAAoJEDy9cKN/1Et0WUQP/RqSnUp6ySmmE+Kc5EOwao2J xiI1qRMm4oc7OX3YlfVAunmk09kFDAh3obaBvmncDMDSZ7FTcZvQ2M9lFVPufTQQ QLMCHFWkF6Jl+Szcq6wAhQ2PBxBtLUjVFhrtY53ihA+KNvlD5Ls8CJYkNVhKWF8O 8bU7djQVH8B6emyBgHOwRQSv1oaUkVIxU+ePik0f8//8rgaHT+jQzYrDvqFC5OJ1 LhFiRdNtMLTt3feQ9nmkpVUBICrwdJecRvpxrVhFzjAVn+7h6M/BWmcrlDFGKW4h xsFVuf2zPLNpl3R0PBUGb5bPFEgywAS7tUkUGSlXxKZpDMg6KmJcogCL0rLQcEnP tODaPH1kj0sOMKdnFnBiaDunHKXlHjdutQGSc+PmidiccXmtAwvrrWupWoVxr3Pk EUD+0Z9G7PngLy4ab7qc8BdujxaFaRdC7llOYqp8R+Z89KRUbFTSfU6I4nlkN7Tm Q+Of1rHzRHNbNPC/34yLQ+ZjEKrB+Don2jeb1aye9ia+sRd2p4a/RgKklnkNhIve IckM145+cLyN3xntfX9IGjIKdwFpYH8ebnt+QvGHlxIPYHgL/wcR2M4JjlHwa4b6 uM4ifeeUWGYqi97hjaP9sAsX3J5EJznU46vPX09xhsmR+6PXgiYw3cUq37lWQ95x 3vSKtYcHJfX2FnIRU8/+ =uBcE -----END PGP SIGNATURE----- _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
