RAM management for multiple links count and data length

[Arepa]

Hello,

I am trying to increase the Peripheral/Central_Link_count to 10 for each or 20 in total and NRF_SDH_BLE_GAP_DATA_LENGTH above 200

I am getting an error when compiling "region RAM overflowed with stack" when using the settings above, I adjusted the RAM,

But I am not sure if it is the same issue :https://devzone.nordicsemi.com/f/nordic-q-a/26448/nrf52832-maximum-number-of-central-links

I can't have more than 14 NRF_SDH_BLE_TOTAL_LINK_COUNT on my app

the latest SDK 15.2 is supposed to support 20 concurrents connections, is it possible?

Details: 

nRF52832

SDK15.2

it is a multi-role app

Hi tesc, I am doing exactly that, changing the SD RAM length and adjusting the RAM size and length for the application.

The issue I am facing is after adjusted the RAM, I got the message "region RAM overflowed with stack"

I tested reducing the heap size, and it allows me compile the project, but I am not sure how it can impact my application,

Hi,

OK. I see. As far as I know none of the SDK examples uses the heap, so reducing it should not be an issue.
