Hello,
On our custom PCB, we’re using an nRF5340 and an nRF7002 via the WM02C module.
In our devicetree, we are using the following QSPI node configuration.
We’ve produced 10 custom PCBs, and on 5 of them the Wi-Fi works perfectly. Both the SoftAP and Wi-Fi Shell samples run without any issues.
However, on the remaining 5 boards, it seems like there are transmission issues (TX). The module is able to perform a Wi-Fi scan and correctly lists all nearby access points with strong RSSI values. But when trying to connect to any of them, it never receives a response from the AP, most likely because the nRF7002 isn’t transmitting anything.
When flashing the SoftAP sample, there are no errors in the log, and everything appears to work correctly. But no devices (e.g., phone or computer) can detect the access point being broadcast.
Does this sound like a software issue, or is it more likely to be a hardware problem?
Here is the device tree and and pcb schematics.
