I’m trying using FC41D chip on Quectel demo boards. The goal is to set one board in AP mode and another one in station mode and exchange data between them. When I try to open socket service with command
the answer is ERROR, typing QIGETERROR, the answer is
+QIGETERROR: 551,"unknown error"
Do you have suggestions?
FC41D in AP Mode
Connect FC41D module with available AP in STA mode:
Start AP mode on module:
Start a TCP listener session on module and check the state.
FC41D in STA Mode
Connect another FC41D module with earlier started AP mode on FC41D module
Open a TCP connection as TCP client and mentioning the listener IP of FC41D_AP
TCP data communication
Send data from TCP client (FC41D STA) to TCP Listener (FC41D AP)
Thank you. It’s working.
I see you use access_mode = 0 (buffer mode). It is possible to send and receive data in transparent mode?
I have firmware version FC41DAAR03A03.bin_202203110937 that I think is older than your.
Where I download the latest firmware release?
Thank you for your support
Yes , transparent mode works on TCP client.
Please share an email address to receive the firmware.
