the trait `NrfTimerExt` is not implemented for `nrf52840_hal::nrf52840_pac::TIMER0` error

Hello,

When compiling my application, I get the following error:

_let ble_timer = BleTimer::init(device_peripherals.TIMER0);	^^^^^^^^^^^^^^^^^^^^^^^^^ the trait NrfTimerExt is not implemented for nrf52840_hal::nrf52840_pac::TIMER0

Here are my dependencies: _[dependencies] rubble = "0.0.4" rubble-nrf5x = "0.0.4" cortex-m = "0.7.3" cortex-m-rt = "0.7.0" cortex-m-rtic = "0.5.9" cortex-m-semihosting = "0.3.7" panic-halt = "0.2.0" rtt-target = { version = "0.3.1", features = ["cortex-m"] } nrf52840-hal = { version = "0.14", features = ["rt"], optional = true }

[features] 52840 = ["rubble-nrf5x/52840", "nrf52840-hal"]_

I compile the app by calling cargo build --features 52840.

Does anybody have any idea what to do?

(not the maintainer) I suspect your problem is that NrfTimerExt is implemented for a different version of nrf52840_pac::TIMER0 than your application code is using. I solved this by using the unpublished version of rubble, you could also figure out what version of nrf52840-hal rubble uses and downgrade to that version in your app.

Here's how to use the latest unpublished version

rubble = { git = "https://github.com/jonas-schievink/rubble" }
rubble-nrf5x = { git = "https://github.com/jonas-schievink/rubble", features = [
    "52840"
] }

Thanks @danielzfranklin !
