Part Number: CC2640
Tool/software: Code Composer Studio
We have two custom cc2640 modules that are working correctly, one has a code based on the peripheral example and the other one is based on the central example. So the one using the central fw is scaning and connecting to the other one.
When the 2 devices are near (<4m) the connection works perfectly, but when you start to move away the two devices, the connection starts to fail and we have to try more times to establish a connection.
Once the connection is established we can move far way and the connection works flawlessly. And when we use smartphones (Android or iOS) to connect to the peripherial one the connection range is much more (it starts to fail connections further away)
We followed the HW design recomendations, we are using the max RF output power (5 db) and we measured the 32.768 kHz clock and the 24Mhz clock in both devices and they are fine tunned.
Is this a HW problem?, can we improve the connection range in SW?
