Hi,

As far as I know, this tablet doesn't not have support for the Bluetooth Low Energy protocol but rather Bluetooth Classic. Which is why you can't see the device advertising.

Hi,

It is of Lenovo tablet M10 and if i run a normal scan on nrf connect from my mobile I can not see the deivce. The device can not be seen by nrf board, nrf connect and even by ubertooth. I have changed the frequency too but still no success.

Exactly which tablet are you using. Could you provide the model number. Also, could you confirm that you can not find the tablet when you use nRF Connect mobile phone application for scanning the advertising tablet?

What do you mean by normal bluetooth connection and normal ble scanner. What are you using to connect when it works? And how are you connecting to the device if you can't even use a "normal ble scanner" for scanning the device.

No, I am not able to see it by nrf connect and not even by normal ble scanner. I can only see it by normal bluetooth connection.

Are you able to find the device if you use the nRF Connect App for Desktop or nRF Connect app for mobile?

Hi,

I assume that you mean that the device is advertising. The advertising packet is the same in 4.2 so it should not be dependent on that version. The reason I asked for the GAP role is that some devices can advertise on the adv channels in a non normal sequence, Could you try sniff on only one channel by changing the Adv hop to only one ADV channel:

it is a slave and when we do a normal bluetooth scanning then i can see the tablet but my sniffer tools can not see the device. Is it due to 4.2 or what

What GAP role is the tablet? Central or Peripheral, i.e is it scanning or advertising?

Hi.

Which version of Wireshark are you using? Are you able to sniff other devices that run newer version of the BLE protocol?
