Can we send BLE packet using nRF52840 dongle?

[kosmos]

Hi, I just got two nRF52840 dongle and it works great as BLE sniffer.

I want to send continuous BLE data (not only advertising) packet and sniff packets between bonded devices. BLE packet can be any random data.

1) Can nRF52840 dongle send and receive BLE data packet continuously? If yes, can you provide a manual or link related to this?

2) Can nRF52840 dongle sniff BLE data packet transmitted by pc or phone? (e.g. Mac <-> Phone(ios/android))
    I downloaded nRF Connect for Mobile in iPhone and I confirmed that sniffer can capture advertising packets. However, I want to sniff BLE data packet between bonded devices (Mac <-> iPhone). I found that Apple (also Google) supports BLE transmission so I can implement custom BLE data to send and receive.

3) Any suggestions would be really helpful to give example environment that can send and receive continuous BLE data packet. (I personally prefer pc-phone example because I can send custom data packet and manage lots of things directly, but if this can be done easily by nRF devices and nRF software, it would be great though)

I would like to follow up on this, even though this is 3 years ago, can the same be done but for zigbee? To send zigbee packets using the nRF52840 dongle? Tried looking online but been pointed towards using nRF connect SDK or zigpy, not sure if this is the right approach though? If you have a repo or a link to point in the right direction, that would be greatly appreciated, thank you!
