nRF52810 as BLE CENTRAL

All of the PCA10040 examples in the SDK can easly be modified to emulate or transferred to nRF52810 hardware. A user guide for this can be found in the SDK documentaion over at the Infocenter. There are no examples explicitly for the nRF52810 because we don't have any Development kits with the nRF52810.

Hello, just a follow up concern.

I am confused with the brief overview of S132,

This line confuses me. If it is stated there that s132 is a protocol stack for nRF52810 and nRF52832, then why is that there is no example in the SDK for nRF52810 using s132?

Also, based on the compatibility matrix of nRF52810, the latest version of the softdevice no longer supports the chip, why is that so?

If it is because of the complication regarding the memory size of nRF52810,hence it is no longer supported on the later version of s132, shouldn't there be an adjustment with the overview of the software to avoid confusion and misunderstanding. Because reading the highlighted statement, it highly implies that the s132 can be used in developing nRF52810 no matter what version it is.

Thank you in advance!

Thank you Simonr for clarification

I'm sorry, but you won't be able to run code from an external flash chip with the SPI interface of the nRF52810. What Turbo J is saying is correct. Your application is too big for the available space. The nRF52810 is not very well suited for acting as a central role, and I strongly suggest moving to the nRF52832 when developing a central application.

Best regards,

Simon

It's a custom board with a 4MB SPI flash

Which external memory?

NRF52810 does not have the QSPI found in the NRF52840, which is the only external interface that could run code.

Thanks for the translation.

Can this problem be solved when I use an external flash? Like placing the app to the external memory?

Relevant line:

Output/Release/Exe/ble_app_blinky_c_pca10040_s132.elf section `.init' will not fit in region `UNPLACED_SECTIONS'

Translation: Your app is too big for the available space (0xD000 bytes IIRC). There is not a lot of flash available on the small chip when the fat SD is in use.

I suggest trying to disable NRF_LOG, those strings can take a significant amount of flash.

Also consider using a larger NRF chip variant...
