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

I see. Seems you have looked into it, so I guess you know that our FDS module implements wear leveling.

Anyways. It is always recommended to use the latest SDK, but it of course depends on how much code you need to port. The ble_app_gls example for nRF52 is in the latest SDK (14.2.0), it uses the RACP characteristic.

0x00000007 is NRF_ERROR_INVALID_PARAM. It is a bit difficult to know what it is without knowing more about what you are doing. What arguments you give to sd_ble_gap_adv_start() and so on.
