Setting Window Offset in a Connection Request

[Torsten Robitzki]

Hello,

I have problems connecting a nrf52 with a TI cc2650. The cc2650 is the peripheral and I can connect to the device from my PC and from some other devices. But when I use a nrf52 eval board that tries to connect to the cc2650, I can sniff the connection request and empty PDUs send by the nrf52, but I do not get any response from the cc2650.

One difference I've found is, that the nrf52 uses a window offset of 0 when connecting, while other devices use values different from 0.

Is it possible to configure the s132 softdevice to use a window offset, othere than 0? This is just to find the cause of the connection problem, so any quick 'n dirty solution would be fine.

kind regards, Torsten

The window offset can be set to a value different than '0' by using the compatibility mode that can be set with sd_ble_opt_set(..). The option for compatibility mode: ble_opt_t --> ble_gap_opt_t --> ble_gap_opt_compat_mode_t

Ups, I have to correct me. That did the trick. Looks like a bug in the cc2650 BLE stack (surprise, surprise).
