Mesh assert error in m_packet.bearer_bitmap events

[Chaabane]

Hello,

I'm using mesh 2.0.1 to test message sending between 2 nRF52840 DK boards.

I'm using a task from FreeRTOS kernel to send messages from the node to the provisionner.

I get an assert because of m_packet.bearer_bitmap is set after sending few messages ( 70, 111 or 200...etc). messages are sent each 2 seconds

I have setup the mesh irq priority to NRF_MESH_IRQ_PRIORITY_LOWEST.

I'm using uint32_t access_model_publish(access_model_handle_t handle, const access_message_tx_t * p_message) to send the messages.

The stack shows that the core_tx_packet_alloc() when the assert happens is call from the QDEC_IRQHandler

I tried to check m_packet.bearer_bitmap before sending data but this didn't help ?

 

Is there a solution to avoid this kind of issue ?

Thank you

I disabled FreeRTOS and I used timre1 to send messages with access_model_publish() every seconde and it is working with now issues.

The timer interrupt priority is set to 7.

I also reduced message size from 13 to 5 and it works with no problem !
