Hello,

I am trying to send data on an udp socket, I am able to see connection on the web service of my cellular provider. First problem, I dont receive answer of AT+QIACT? then in buffer send mode, I receive the >, I write correctly the data, but I never receive the SEND OK. Is there something wrong in the following sequences ?
Thanks in advance

Update of behaviour,

When I use AT+CGACT=1,1 and check with AT+CGACT?, I am able to receive +CGACT: 1,1, and also +CGACT for all context until 16.
The Socket open is still ok, but still no answer from modem for data I sent after received the ‘<’.

Hello there,

I have to test but I think that the AT+QICFG=dataformat should help me ! I will try tomorrow and let you know !

4

Unfortunately … I have also no answer from the module when I send this AT command, I tried an AT+QICFG?, same result, no answer … Please help me …

5

Update, I tried a QPING and network answered me OK, my last blocking point is QICFG that doesnt answer me now !

6

For informations, QICFG=dataformat passes when I send it just after QCFG=band …
Now my last problem is the non answer of hex send when I ask for QISEND=0,48
