如何让wifi和bt同时工作

今天写了段代码,希望让wifi和bt同时工作。但是很不幸,一直未能成功。
wifi模式:STA
bt模式:主

情形一:先启动wifi,然后启动bt
结果: wifi不能连接到ap,bt工作正常

情形二:先启动wifi,待wifi连接到ap后再启动bt
结果:wifi启动后可以连接到ap;但是启动bt后,bt工作正常;但是wifi会断开,再次连接任然失败

情形三:先启动bt,然后启动wifi
结果:wifi不能启动,bt工作正常

附件是编译时使用的sdkconfig.h

请问如何才能让wifi和bt同时工作?

IP_FORWARD dose not work

IP_FORWARD has been set to 1 in \lwip\include\lwip\lwip\opt.h at first. Then I run esp32 wifi in sta+ap mode. But esp32 could not forward ip package from ap interface to sta interface.

BLE rssi is too strong

I set esp32 to gatt client mode. It scanned some iBeacon messages. But the rssi of iBeacon is too strong. eg: iBeacon rssi is -29dbm when the distance is 1 meter from esp32 while calibrated value is C7 ( -57dbm)
