Combine multicentral and muliperipheral

[Tommy_Li]

Dear All:

           Our team are ready to develop a project with multicentral and multiperipheral

           The project topology image lists as follow:

          

           I want to ask how many ram it will cost at least, Does nRF52832 can fullfill those requirements? 

           Thanks in advance.

Hi,

This should be possible on the nRF52832, yes. The s132 SoftDevice on the nRF52832 can handle up to 20 concurrent connections, so the 7 connections are well within limits.

A quick check based on the ble_app_multirole_lesc_s132_pca10040 example indicates 2 peripheral + 5 central gives SoftDevice RAM requirement of 0x4A20 = 18976 bytes, or around 19 kB. This may vary depending on size/number of characteristics, etc., and application side RAM requirements are not included.

Regards,
Terje
