racp nrf52 external memory

[matthk]

Hello, I have in a multi-sensor application some actual data (including RTC) which appear continuously and which have to be saved in an external RAM connected by I²C. All these data for one time take 20 Bytes and build a data set. Up to 1024 data sets shall be saved; an external device like a Tablet or a Smartphone shall read them all or only a part of it. I saw the interesting blog devzone.nordicsemi.com/.../ but unfortunately this is for nrf51 and with encryption - in my project the encryption is planned much later. My questions are:

• Is there any example with code, which shows how to implement this?
• Is it possible to preview already the encryption for the future? Thanks in advance

Hello Petter, the call to this function is done with the pointer to the adv_params struct at address 0x2000ffac; all values in this structure are 0, only interval is =40 and timeout = 30. In the channel_mask I see ch_37_off, ch_38_off and ch_39_off but all with value 0. The second parameter in the function call is m_conn_cfg_tag with value 0. Are these information sufficient for a small analysis?
