ESB after S132 disable

[Wojtek]

I am having trouble with using shockburst (based on microesb from github) after disabling S132.

When I use microesb with no SD, i just do nrf_drv_clock_init(), start lfclk and hfclk - after that just uesb_init and I can transfer/receive data succesfully.

In my second app that uses S132 I disable SD, then nrf_drv_clock_init() (here i ignore SD not enabled error), and start lfclk and hfclk - then just uesb_init() and my radio is not transmitting when requested. Should i enable something more to use ESB?

Hi.

The driver is (for some unknown reason) designed to be used together with a softdevice. It will be fixed in a future version.

In the meantime, you can follow the ESB example (now included in the SDK), and start the timer manually

void clocks_start( void )
{
    // Start HFCLK and wait for it to start.
    NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_HFCLKSTART = 1;
    while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);
}

I was almost 100% sure that my HFCLK is working but it seems it was not. Now my radio is transmitting :) Thanks Anders!
