GAZELL and BLE simultaneously activated not working

[Christophe_]

Hello Nordic Team

I am using SDK 3.0.1 with a nRF52DK to develop a firmware that can be switched from BLE mode to GAZELL mode and vice versa over a command sent via UART port.

My project works good in GAZELL mode, but BLE is not working.

With the help of this article  RE: Gazelle and BLE I found out that if I comment out the following lines in gzll_glue.c, the BLE part is also working correctly.

    IRQ_DIRECT_CONNECT(GAZELL_TIMER_IRQN,

               CONFIG_GAZELL_HIGH_IRQ_PRIO,

               gazell_timer_irq_handler,

               GAZELL_HIGH_IRQ_FLAGS);

    IRQ_DIRECT_CONNECT(RADIO_IRQn,

               CONFIG_GAZELL_HIGH_IRQ_PRIO,

               gazell_radio_irq_handler,

               GAZELL_HIGH_IRQ_FLAGS);

And with the help of this article  RE: Gazelle and BLERE: Gazelle and BLE I changed the 2 gzll_glue.c lines with following code:

    ARM_IRQ_DIRECT_DYNAMIC_CONNECT(GAZELL_SWI_IRQN, CONFIG_GAZELL_LOW_IRQ_PRIO, 0, reschedule);

    ARM_IRQ_DIRECT_DYNAMIC_CONNECT(GAZELL_TIMER_IRQN, CONFIG_GAZELL_HIGH_IRQ_PRIO, 0, reschedule);

    ARM_IRQ_DIRECT_DYNAMIC_CONNECT(RADIO_IRQn, CONFIG_GAZELL_HIGH_IRQ_PRIO, 0, reschedule);

 

    irq_connect_dynamic(GAZELL_SWI_IRQN, CONFIG_GAZELL_LOW_IRQ_PRIO, gazell_swi_irq_handler, NULL, 0);

    irq_connect_dynamic(GAZELL_TIMER_IRQN, CONFIG_GAZELL_HIGH_IRQ_PRIO, gazell_timer_irq_handler, NULL, GAZELL_HIGH_IRQ_FLAGS);

    irq_connect_dynamic(RADIO_IRQn, CONFIG_GAZELL_HIGH_IRQ_PRIO, gazell_radio_irq_handler, NULL, GAZELL_HIGH_IRQ_FLAGS);

Also here everything is fine in GAZELL mode, but doesn't work in BLE mode. If I comment out the 3 last line of code BLE work fine.

Please note that if in BLE mode the methode gzll_glue_init is not called.

So how to connect really dynamicaly to irq's ?

What am I missing ?

Hi,

I am very sorry for the delayed response to your questions. Key person is away, and we expect to get back to you early next week. I am sorry for any inconvenience.

Hi,

Unfortunately we do not have any sample of this, but it looks like you are on the right path. Have you enabled dynamic interrupts for MPSL as well? (see the config in this unoficcial sample which demonstrate ESB and BLE)

Br,

Einar

Hello Einar,

Thank you for your answer, it works fine now.

In the config file, to the following 2 lines I added the 3 new lines and now I can select at startup via buttons the running mode BLE or GAZELL.

Existing:

CONFIG_DYNAMIC_INTERRUPTS=y

CONFIG_DYNAMIC_DIRECT_INTERRUPTS=y

New:

CONFIG_MPSL=y

CONFIG_BT_UNINIT_MPSL_ON_DISABLE=y

CONFIG_MPSL_DYNAMIC_INTERRUPTS=y

I will look now how to switch the running mode while BLE or GAZELL is active.

Once more thank you for your help.

Best Regards

Christophe
