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

Do you have an email address where I can send a zip-file?

Hello Petter,

I tried to set the second parameter to 1: ret = sd_ble_gap_adv_start(&adv_params, 1);

and then the advertising works.

But I have no explication for that. The standard call is ret = sd_ble_gap_adv_start(&adv_params, m_conn_cfg_tag);

where m_conn_cfg_tag = 0...

Does this mean that a default connection is missing?

Great that you found a workaround. I'm not really sure why you get an error. I tried your setup with 0 and it seems to be working fine. Would it be possible for you to upload a complete project that exhibits the behavior?
