Hi,
We have a product with nrf24L01p Gazell (LastChangedRevision: 133) that acts as a Host. At the moment I'm trying to pair with this host via a PCA10040 Devkit (nRF52832) that acts as a device. For this I'm using the SDK15.3 example: gzll_dynamic_pairing_device_pca10040
Should this setup pair out-of-the-box? Or can I expect some compatibility issues with this setup? At the moment it does not pair at all. Secret key, PIPE addresses and so on are equal.
Thanks! I suspect that the issue can be in the pipe addresses, this part:
/*****************************************************************************/
/** @name Default Address configuration */
/*****************************************************************************/
/*
Corresponds to Legacy nRFgo SDK Gazell config:
#define GZLL_DEFAULT_ADDRESS_PIPE0 {0x01, 0x04, 0x07, 0x0A, 0x0D}
#define GZLL_DEFAULT_ADDRESS_PIPE1 {0x02, 0x05, 0x08, 0x0B, 0x0E}
#define GZLL_DEFAULT_ADDRESS_PIPE2 3

We are using the "legacy" pipe configuration, how should I modify this part to use the legacy addresses? During the pairing the host and device are on top of each other 
Or should this part also be backwards compatible already?
Edit: I'm able to pair between 2 NRF52 dev kits, but that's obvious of course.
