Hello Nordic supporters!
We are developing a system using BT Mesh alongside a software DALI protocol driver with certain timing requirements.
Right now we're trying to figure out how strict the timing requirements of BT Mesh are compared to normal BLE, and how they would interact with the DALI requirements. We were thinking there could be a difference since BT Mesh is advertising based and not connection based. We would appreciate some help in finding exact numbers.
For the driver we're considering, these timing requirements are given:
- One function must be called at least every 5ms by the user application and must not be blocked (e.g. through storage of persistent data).
- Another function should be called every 10ms to ensure functionality
During these function calls the driver would be doing bit-banging on the gpio, which we would like to not have interrupted by the BT part of the code.
Do you think these requirements could realistically be satisfied while running BT Mesh on an nRF52840?
Thank you in advance,
Einar
