I would like to use ODIN-W2 exclusively in PPP mode and communicate with it over UDP port 25. Everything works expect uploading certificate using command AT+USECMNG for use with EAP-TLS.
I can send AT+USECMNG=0,1,"cc",1196 and module response correctly with a prompt >. Then I send a certificate. After a while, odin responses with ERROR and it does not respond to AT commands anymore. I must restart PPP to reactivate it again. I have EVK-W262U and it also blinks red after an error response.
I have firmware 188.8.131.52. I'm using hardware flow control which is needed by the datasheet.
Is there a possibility to upload certificates over PPP?
