We have SODAQ SARA R412M Board and we are using DU NBIOT sim. Each time when we are establishing the network for NBIOT, the module is getting connected by default with the 2G network. Below are the AT commands we used for establishing NBIOT.
AT+USOST=1,“220.127.116.11”,8891,16,“16 bytes of data”
We have contacted the Network provider (Du UAE) and they told us that there is some commands missing. Please guide us.
Also, please let us know if there is any AT commands which confirms the connectivity to the NBIOT network.
