Hi,
PANS libraries are currently compiled on top of eCos RTOS. Would it be possible to get them compiled for Zephyr RTOS instead ? Zephyr is a very active project from Linux Foundation and it provides a nice Bluetooth Mesh implementation for NRF51 & NRF52 SoCs.
We have an RTLS project in mind where BLE mesh would fit very nicely.
Br,
Franck
