Hello,
I am designing a LTE-M GNSS Tracker, that should also be able to scan for WIFI APs. I dont need to use LTE and WIFI at the same time, but rather like that:
- Connect to LTE, download AGPS Data.
- Go into LTE PSM mode.
- Start GNSS and aquire Fix
- Deactivate GNSS
- Activate WiFi with nrf7002 and scan for APs
- Deactivate Wifi
- Come back from PSM Mode and send the GNSS Data + WIFI APs over LTE to my CoAP Endpoint.
For that, I am designing a board using the NRF9160, together with the NRF7002 WIFI IC. I took the pinout from the NRF9160DK and NRF7002EK Shield. I have two questions:
- Is there anything important to notice for the pinout, when connecting them both? Especially, to allow really low power. I need to be able to "deactivate" nrf7002, when not in use. Here is a snippet from my schematic. This should match the NRF9160dk with NRF7002 Shields connections.
- Is it possible, to have WIFI Scanning and LTE activated in the project? I see, that the example AssetTracker v2 overlay file tells only WIFI scanning. I am not planning to use them simultaneously , but rather sequentially.
Any help from experience or from the dev team is highly appreciated. Cheers
