Quectel BC66, How to improve very-first-attachment time
As you know the very-first-attachment to the network can take multiple minutes. Sometimes this creates problems in the production process.
Out of this reasons we are looking for possible measures to improve the very-first-attachment time.
- Before activating radio module Set APN with AT+QCGDEFCONT rather than **AT+CGDCONT
- Set frequency band explicity with AT+QBAND
- Configure first APN, fequency band and mobile operator ID before switching on automatic attachment
