nrf sniffer all packets "ERROR: packet creation error"

[Marcelo Aleks]

Hello,

 

  i am trying the nrfsniffer  3.0, but all the packets seems to being dropped.

  I am using:

  * BLE400 with nrf51822 module (firmware flashed with stlink )

  * Linux kernel 5.5

  * python 3.6.9

  * wireshark Version 3.2.2

  Only the firmware versions sniffer_pca10001_129d2b3.hex and sniffer_pca10001_129d2b3.hex are working. The supposed correct (sniffer_pca10028_129d2b3.hex) is not transmitting data.

  Has anyone solved this issue ?

I am not aware of any issue no, do you have more than one nRF51-DK you can try on, what is the DK version of the nRF51-DK?

Can you try to plug the nRF51-DK to another USB port (e.g. not through a USB hub)?

Best regards,
Kenneth

Hi @Kenneth,

  i am not using nRF51-DK.  I tried flasing the firmware with  stlink using a nrf51822 as module.  The serial was opened using the ble400 board or with a USB to UART connected direct to the n51822 pins. 

  Have you tried the PCA10028 firmware. Is it working in the nrf51822 modules ? Because this one do not even send anything to the serial.

  

[Kenneth]

Hi,

The PCA<nnnnn> refer to a specific pcb board, in this case:

PCA10001 is the nRF51-EVK (no longer in production), but you can find schematic here:
https://devzone.nordicsemi.com/f/nordic-q-a/43868/where-can-i-find-nrf51822-ek-pca10001-schematic/171849#171849

PCA10028 is the nRF51-DK (still in production), you can find the schematic here:
https://www.nordicsemi.com/Software-and-tools/Development-Kits/nRF51-DK/Download#infotabs

I will assume both firmware you refer to rely on being run on the specific hardware they have been built for, if the hardware is not the same (e.g. different uart pins or clock source), then it may no work no.

Best regards,
Kenneth

Hello Kenneth , do you know if is there any issue about baud rate ?  

I am using nrf52840 for development , but i really would like to use a lot of old 51822 as sniffer to capture mesh packets.  

Are you planning to release the sniffer source code ?

Best regards,
Marcelo Aleksandravicius

[Kenneth]

You will need to use the same pins as the pca<nnnnn> hex file you program. You would need to refer to the schematic for the pca<nnnnn> which gpios are used for UART.

That is not likely no.

Kenneth

Thanks
