Radio pin interrupt sometime not registered

[RobTWTG]

When further investigating this old issue: #77
I observed that sometimes a RX_DONE task is not finished properly, and the lbm will still panic like this:

[ERR ][LHAL]: function: rp_callback, line: 443 [ERR ][LHAL]: RP_FAILSAFE - #2

I noticed that in the rp_callback function the 1st thing that gets done is smtc_modem_hal_disable_modem_irq( ); disabling the timer and pin interrupts.

With overlapping tasks (like managing ping slots for class B) It looks like there is a chance that radio pin interrupts can be missed. Because rp_callback is called periodically.

I ran a simple test removing all functionality from smtc_modem_hal_disable_modem_irq so not disabling the interrupts anymore, and the panics disappeared.

Hopefully this can get looked into.

Many thanks,

Hi,
Thank you very much for your feedbacks.
Could you please let us know which MCU you are using and the implementation of smtc_modem_hal_disable_modem_irq( ) function ?
Many thanks,
Best regards,

@opeyrard was this issue closed because of the recent (version 4.8.0) change to rp_callback ?

I have an issue with smtc_modem_hal_disable_modem_irq and smtc_modem_hal_enable_modem_irq not being called at all after upgrade from 4.5.0 to 4.8.0 and I just want to know if I should raise a new issue?
As an example. In version 4.5.0 smtc_modem_hal_enable_modem_irq would get called prior to transmission, which is not the case anymore causing no TX irq to be triggered.
The only references I can find to smtc_modem_hal_disable_modem_irq and smtc_modem_hal_enable_modem_irq are now in fifo_ctrl.c.
