I want to use i2c and uart0 simultaneously in nrf52832 .

[subhra]

RTC connect  through I2C and GPS connect to UART.
I am getting large amount of data from gps contentiously .
In the mean time i should read time from RTC .
But i am getting Wrong data from RTC .

When uart do not receive  data I2C data is correct .

First step is to determine if this is a hardware or a software problem.

Have you looked at the I2C lines to see if they are being disrupted ?

What, exactly, goes wrong with the I2C ?

[subhra]

Thanx for response.

I checked hardware , it's fine .
I am using nRF5_SDK_15.0.0_a53641a  example code .
Packet receive by I2C bus is not perfect .
I am getting wrong RTC value .

Could you explain your project in more detail? What examples from the SDK are you using, and what modifications have you done to it? Maybe you could add some relevant code snippets?

What, exactly, do you mean by that? Please explain!

If you have scope or analyser traces - post them.

In what way(s), exactly, is the RTC value "wrong" ?

Hardware schematic would also be useful.
