Multi-link Central on NRF51802

[M.A.N.]

Hi

I'm planning to connect three different BLE peripheral like Heart-rate sensors, Health Thermometer, and Blood Pressure to a Central BLE device.

I'm using a small customized module "ND02-C" that is based on the NRF51802QFAAA0 chip, I can program it and run it as a peripheral like HRS right now.
but as I try to use program Multi-link central examples, I got low space size errors at compile, I use S120 and my chip flash size is 256KB and RAM size is 16KB.

can I use this chip for a small multi-link app for at least 3 concurrent connections? if yes how and with what Softdevice?

if no, is there any other way to customize the main program or Softdevice to fit it in the chip?

I also need to set up and collect devices data over USART too.

what is your recommendation?

Hi,

 No, compiling this example with 3 links requires 22kB RAM. Go for the 32 kB RAM nRF51 variant, or alternatively, upgrade to the nRF52 series, and use e.g. nRF52832 instead.
