nr52832 nfc read and write not working properly with i2c

[pd@learner]

Hi, I am using nRF52832 with sensor, nfc and  Softdevice S132 v3.0.0 to advertising packets .The sensor is interfaced with nrf52832 using twi interface. I have referred examples\nfc\writable_ndef_msg to read and write data from nfc.  I am writing url to nfc tag and read  it from tag. When I Comment sensor  code , nfc read and write operation work properly. But When I used sensor code then after writing data to tag it reads new data once then it reads old data.

Thanks in Advance

Hi.

Which sensor are you using?

Have you tried debugging the project and looked where you end up in the code?

Best regards,

if I used init_twi()  and comment remaining sensor code then also read operation shows old data after writing new data.

is there any relation between nfc and twi?

Hi.

Do you have the opportunity to upgrade to SDK 15.3?

There has been many workarounds and bug fixes from SDK 12 to SDK 15.3.

This could fix your problem perhaps.

Best regards,

Thanks for your suggestion. 

No ,  I don't have opportunity to upgrade SDK.

But  I can't understand how did twi affect nfc operation ?
