Can't connect to sensor using nrf52840 Dongle

[Pranav Nad]

Hey guys,

I have recently been using the 2.0.0 SDK to develop the nrf52840 dongle to communicate with a sensor. I am unable to connect to a pressure sensor and I have tried it on multiple pressure sensors of the same brand type and I am still not able to connect. For a bit more context I am able to connect to other sensors other than this specific pressure sensor but for some reason, I cannot connect to this sensor. Here is the debug log I got on the putty terminal. 

I have a feeling it might have to do with my connection parameters right now. The connection interval minimum and maximum are 100 ms, the latency is 0ms, and the supervision time out is set to 400ms. Does anyone know why my dongle might not be connecting to this sensor but is able to connect to other sensors? thank you

What is the transport layer that you are using with this pressure sensor? (uart/spi/i2c). That will let us know which driver you are using. Also mention the sdk version and the name of the pressure sensor so that anyone else who used it before can respond here.

It might help if you can check the data lines on this sensor (using oscilloscope or logic analyzer) to see if there are some redundancies in the sensor setup or its responses.

Hey, 

I figured out the issue, I just had to increase the connecting timeout. 

Thanks for the help!

thanks for letting us know Pranav.
