nRF52811 w/ soft device s140

[[email protected]]

Hi there. In order to up to 20 concurrent onnections to the device, it was necessary for us to switch from the s112 to the s140. 

I believe I am messing up the flash placement of this and am not understanding the guides so well.

I was able to discern correctly;

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x30000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x6000

FLASH_START=0x27000

but the last three I didn't understand how to sort those out.

Not sure if this is related but when I tried to build the project the following error was displayed;

#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)"

Using sdk 17.0.0.2 with SES.

Thanks in advance for any assistance.

So played around with this a bit and s140 is quite a bit bigger. Don’t suppose there’s a way to expand s112 to support more peripheral connections?

Here’s a cool video of us connecting 4 phones to the device.

Btw, appreciate the support.

Hi Kevin, 

Torbjørn is away for a week, so I will just drop an answer here.

No there isn't an option to change the max number of peripheral the S112 can support. Unfortunately there will be no new development on the legacy Softdevices as we moved to nRF Connect SDK from 3 years ago.
