Master and Slave Implementation on nRF52810 ?

[DD_connectivity]

Hi,

In case of nRF52810, is it possible to implement both Master and Slave Mode ?

Also, this has do be done while the product being able to work with AT Commands.

Thanks.

Hi,

By Master and Slave mode, are you referring to BLE? The nRF52810 is compatible with s132 softdevice v5.1. This softdevice supports both Peripheral and Central roles. Note that the Flash and RAM sizes of the nRF52810 will limit what functionality the application can utilize. Using the s132 softdevice will take up most of the available space, leaving little room for the application.

We do not provide any AT Command features. I know some module partners implement this, but all chips from Nordic are delivered with blank flash that you need to program yourself.

Alternatives to AT Commands are our serialization solution and the BLE Interactive CLI example.

Best regards,
Jørgen

Hi Jorgen,

Thanks for your feedback.

Considering we move ahead with nRF52810.

s132 requires 136KB Flash.

Can you help me with the memory requirements of Serialization solution and CLI and which one do you recommend ?

Also, does the above method gives better performance than AT Commands ? 

Also, can you please guide me to a document where in i can find comparative analysis of using AT command vs. Serialization.

Thanks in advance.

I built the s132 UART-HCI connectivity FW for pca10040 board in SDK 14.2.0, the flash and RAM usage is like this:

The BLE CLI example is not available in SDK 14.2.0, this was first introduced in SDK 15.0.0.

I think that you would have problems with fitting concurrent central and peripheral features into a nRF52810 chip. If you require this, I would rather recommend you to go for the nRF52832.

Since we do not have any AT command solutions, I cannot give any specifics on performance. I would not expect the serial protocol to affect the performance much if you run UART on 1 Megabaud or SPI on 8 MHz.

Hi Jorgen,

Noted. Thanks.
