Hi,

Which sensors do you use?

[quote user="dejans"]Could you provide more information about your application?[/quote]

What is your application supposed to be doing? Is your application based on any of our Bluetooth samples? How often do your sensors send data? When are sensors expected to send data? Do sensors send data one by one? Could you provide some additional details?

[quote user="JourneymanWizard"] The sensors send data from an IMU to a PC.[/quote]

For testing, have you tried to use only one or two BLE sensors instead of three? Is the error still there when you use one or two sensors?

[quote user="dejans"]Which NCS version do you use?

Please provide NCS version that you used in your application.

Best regards,
Dejan

The previous logs were captured in an engineering office space with the sensor and PC ~1m apart and the sniffer a few cm away from the sensor.

I am using the nRF52-DK SDK for packet sniffing.

The application is intended for outside (sensor) use. The sensors send data from an IMU to a PC.

Unfortunately the sensor does not generate a log.

Hi,

Based on the Bluetooth Spec v5.2, Vol. 6, Part B, Section 5.3, your issue seems to be related to collisions where link layers of master and slave initiate incompatible procedures.

It might be beneficial to get more information about your setup and environment in which devices operate.

Which NCS version do you use?

Could you provide more information about your application?

Could you show application log when the issue occurs? Are there any errors in the log?

Best regards,
Dejan
