problem in compatibility between SD and Mesh SDK , also FLASH and RAM memory for the NRF52810 and NRF52832

[turki]

Hi

Actually i have a big project and have a problem in the estimation of FLASH and RAM memory for the project

i ma going to implement the mesh SDK with the BLE Stack because there will be a smartphone connexion with the server while the mesh network is on.

- my client want to use the nrf52810 which uses S112. However we want to use S132 but the problem that there is no compatibility matrix for Mesh SDK and Softdevices.

- i still don't know how much exactly FLASH memory need ressources in S112 V2.0 and S132 V6.1.

- How much flash and RAM memory does the Ble Stack consume and Mesh SDK separatly ??

- how much a node can consume in the provisionner , client , server

PS : i am going to implement a client role with the Provisionner so how much i need RAM memory ??

Thank you

You can't use the Mesh SDK without the BLE Stack!

No, you really don't want to do that!

Examples of memory usage are given in the above.

thank you

what about the compatibility of S132 and S112 with Mesh SDK and their memory requirement in latest version because they are not indicated in the specifications neither in the release notes .

Also Ble Stack consumption and the nodes in the mesh  ? 

i will be glad to know the correct number because it's a little bit critical for me 

Best Regards,

The Mesh SDK does clearly state the supported SoftDevices  - and the specific versions required.

If it's critical, then just don't use the nRF52810!

IMO,the risk is just too high.

Again, see: https://devzone.nordicsemi.com/f/nordic-q-a/29316/mesh-sdk-for-nrf52810/155037#155037

Note that S132 is now qualified for nRF52810:

ok thank you very much 

even if i 'am going to work with the nrf52832 ,

is it posssible to know answer for the other questions ?  ( SDK mesh and ble stack consupmtion , also nodes consumption on the provisonner  ) 

sorry for bothering and thank you 

[awneil]

There is some indication of resource usage in the SoftDevice documentation, but I haven't seen anything for the Mesh.

Hence the suggestion to start with nRF52832 - then see if you can optimise later ...

ok Thank you for your help
