Hello,
I'm facing an issue with Wi-Fi connectivity on my custom board equipped with nRF7002 and nRF52840. When I attempt to connect using net_mgmt(NET_REQUEST_WIFI_CONNECT), I consistently receive an error code of -134. The error appears almost instantaneously, seems like net_mgmt might not even initiate the Wi-Fi scanning process before returning the error.
But everything functions flawlessly when using the shell example for Wi-Fi connection and pinging 100 times.
I have tried searching the error of net_mgmt but it is closed source
I would greatly appreciate any insights or suggestions from the forum.
I've already tried the following:
- Verified the connection between nRF7002 and nRF52840 matched the device tree config.
- Verified my Wi-Fi configuration (SSID, security type, password, not hidden)
- Look up Network Management API documents (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/connectivity/networking/api/net_mgmt.html#c.net_mgmt)
- Verified power for the nRF7002 and nRF52840 (Power Supply 3.1V 1A)
- Increase CONFIG_NET_MGMT_EVENT_QUEUE_TIMEOUT to 5000
- Set hotspot to 2.4GHz open network and update wifi_connect_req_params to WIFI_SECURITY_TYPE_NONE
Questions:
1. What does net_mgnt error code mean?
2. What is the difference between shell example "wifi connect <ssid> <password>" and
Here is the error message
*** Booting nRF Connect SDK v2.5.1 *** [00:00:01.520,538] <err> Lesson4_Exercise1: Connecting to Wi-Fi failed, err: -134
If I further decrease CONFIG_HEAP_MEM_POOL_SIZE=103600, the code produced same error code but more error message were shown.
