I saw some strange behavior of "ubus call luci-rpc getWirelessDevices" in master, it did not crash but showed wrong values or mixed some up like the BSSID contains the SSID. I did a clean build and now it is working fine for me. I haven't seen this in 19.07. I assume this is related to the changes: https://git.openwrt.org/?p=project/iwinfo.git;a=commitdiff;h=bf2c1069a7f14d1af1e02c8edd2b7338f0355ac8 https://git.openwrt.org/?p=project/rpcd.git;a=commitdiff;h=efe51f41d6288fa8503cc4f2efb37a777767d505 https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=8fb6be73b552618567dcfcb1eee3ffbb7deadb7e https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=2d80f7e836b5a04b214cc7f00c73517b959712ca I saw this: ------- "iwinfo": { "noise": 0, "channel": 36, "country": "40:31:3C:02:8F:BA", "phy": "\u0001\u0004\u0010\u0010\b\u0001", "txpower": 20, "txpower_offset": 0, "frequency": 5180, "frequency_offset": 0, "hwmodes": [ "ac", "n" ], --------- Hauke
