is the nrf52840 is 6lowpan radio compatible.
is the nrf52840 is 6lowpan radio compatible.
6LoWPAN is not a physical layer. Maybe you can explain a bit more about what you want to achieve?
Instead of ble is it possible to use 802.15.4 in the physical layer ,if yes which radio module i should use with the raspberry pi to act as a border router?
Yes, the nRF52840 supports 802.15.4.
but the raspberry pi does not have 802.15.4 communication ?and can i use the softdevice used for the iot sdk or must i use s140 to support 6lowpan
