Hello, I have a question regarding coexistence of WiFi and Bluetooth in my notebook. I have a rtl8723de chipset, which comes together with a bluetooth chip on the card. The driver is not yet supported by the kernel, but in my understanding, the driver provided at https://github.com/lwfinger/rtlwifi_new is supposed to be merged at some point into the kernel. I'm using that driver for getting the wifi part running, and while the wifi works fine, I have troubles with the bluetooth part, due to very poor signal. I have the the following modules all loaded: rtl8723de 102400 0 rfcomm 32768 16 btcoexist 454656 1 rtl8723de phydm_mod 880640 1 rtl8723de rtl8723_common 24576 1 rtl8723de rtl_pci 36864 1 rtl8723de rtlwifi 163840 5 rtl_pci,rtl8723de,btcoexist,phydm_mod,rtl8723_common mac80211 651264 2 rtl_pci,rtlwifi cfg80211 622592 2 rtlwifi,mac80211 btusb 45056 0 btrtl 16384 1 btusb btbcm 16384 1 btusb btintel 20480 1 btusb bluetooth 393216 38 btrtl,btintel,btbcm,btusb,rfcomm Both the wifi and bluetooth are neither hard nor soft blocked by rfkill, then the signal for bluetooth is really poor. That means I can connect to a bluetooth device if it is lying physically on the notebook, i.e. a distance of 3-4cm seems ok, the bluetooth connection works. Once I move the bluetooth receiver (headset) further away the connection is lost. Soft-blocking the wifi with rfkill the bluetooth signal works as expected (distances of at least 3m through walls are no problem). Once I unblock the wifi, the bluetooth connection is lost instantly, and works only in a distance of a couple of centimeters again. I reported the problem already on github for rtlwifi_new, but I was told, that you could maybe provide better help (the original issue is here): https://github.com/lwfinger/rtlwifi_new/issues/382 I get the following output for `lsusb -s 001:005`: Bus 001 Device 005: ID 0bda:b009 Realtek Semiconductor Corp. I'm running kernel-4.17.14. Any help, what the problem could be is appreciated. If you need further information, let me know what output can be useful, since I'm out of ideas what else would be helpful. Cheers Andreas
