I’m using EG915U-EU at EG915U-E-TE-A mounted in UMTS<E EVB KIT.
I can send/read text messages and make a call (all via AT commands). But when i call to the sim card number in the module, the call is rejected after one ring.
After a few tries, I changed the option Network Search Mode Configuration to GSM (2G)
AT+QCFG=“nwscanmode”,1,1
Then i can call to the module and got RING and +CLIP notification on uart.
So… why calling from module is working on LTE but call to module is not?
Any ideas?
Module firmware is:
EG915UEUABR02A04M08_01.001.01.001
Hello It seems that I have a similar problem.
when I set AT+QCFG=“nwscanmode”,3
The module stops receiving calls or making calls. I wanted to test VoLTE and SMS over4G.
SMS can be sent and received when the network scan mode is st to be 3: LTE does that mean the SMS is being sent over LTE?
This is the firmware version that I have:EG915UEUABR02A05M08
is this the latest one ? if no please code you send the last firmware to me as well.
I am testing MQTT protocol on a EG915U module with firmware version EG915UEUABR02A05M08
I am experiencing the following behavior: as a subscriber to a specific topic, the modem is able to receive up to 16345 bytes: even one more byte and the modem does not receive data anymore and need a reset (AT+CFUN=1,1) and the MTTQS commands have to be resent to estrablish connection with the broker again.
I have performed same test on an EG912Y-EU module with a firmware revision EG912YEUAAR01A08M16 and the same behavior occurs at more than 128KB.
I need to be sure to receive at least 64KB of data via MQTT. Why this limitation on EG915U? Can be a firmware problem?
I can provide more information if you need it to support me somehow.
