Radio not responding after transmitt 24KB

[František]

nrf52840 

sdk for thread and zigbee 2.0

windows

segger studio

in example simple coap cilent and simple coap server

I create my own packet error test through coap requests. I am sending 16B data (+4B header). 1199 packets send without problems. (1200*20 = 24 000)

Then packets stop sending but there is no error. I try change COAP to UDP but problem still remained. I changed size of packet but after 24 000 B again not responsing. After this problem MCU recover only with reset. But there is no eroor or no problem in debuger.

coap sending packet every 1sec and I using peripherals: UART(gps), TWI(display),  and drv timers

Hi.

We have a new version of the Thread and Zigbee SDK out if you like to use that one. I recommend it.

Are you running confirmable or non-confirmable CoAP?

Have you checked that you're not running out of buffer?

Which buffers do you use? Can you check with the cli command bufferinfo?

Could you share your project?

Best regards,

Andreas

I use non-confirmable CoAP.

Buffers was OK when I chceck bufferinfo through CLI. 

When I dont use peripherals SAADC and TWI comunication is succesfull. 

When I use only SAADC, radio send 1000 x 16B packet and next nothing. 

I use SAADC like in peripheral example from SDK.

Hi.

How does it behave if you use a bare-metal environment?

Best regards,

Andreas
