PCA10040 doesn't work

[SyMo]

Dear technical support team,

I'm using a PCA10040 board to sniff BLE packet.

Following the document named "nRF Sniffer for Bluetooth LE v3.0.0", I managed to see some packets on wireshark during several seconds (arround 30s).

After that, the board stopped brutally and now, is impossible to have correct behaviour (none leds are on or blinking).

However, when I power on the board with the "BOOT' button pushed, a window explorer appears on my PC (see attached file) and LD5 is blinking.

Do you have some ideas to help me on this issue ?

With best regards,

Sylvain.

Hi,

If you press and hold the "IF BOOT/RESET" when powering the board, it will enter bootloader mode for the interface MCU (entering the bootloader for the Segger J-Link programmer on the board).

Instead of starting the board that way, try powering it the normal way and try the following command from a command line such as cmd.exe:

nrfjprog --recover

You can also try to install the latest J-Link Software and Documentation Pack from Segger, then use the program J-Link Configurator to upgrade the interface MCU firmware to the latest firmware version, to see if that improves the stability.

Regards,
Terje
