Clear Stored Network Information

I am trying to perform testing of the initial registration process because I am seeing long initial registration times. My development kit has stored the network information so now it connects quickly, which is the desired normal use case. However, I would like to clear the network information so that I can perform testing. Is there a command or procedure for clearing this information from the BG95?

Hi @William_Brown

You can clear historcial infos with following commands:
GSM: AT+QNVFD=“NV/item_files/modem/geran/grr/acq_db”

LTE : AT+QNVFD=“/nv/reg_files/modem/lte/rrc/csp/acq_db”

NBIoT: AT+QNVFD=“/nv/reg_files/modem/nb1/rrc/csp/acq_db” Note: Hardware reset

Clear LOCI(RPLMN): AT+CRSM =214,28542,0,0,11,“FFFFFFFFFFFFFFFFFFFFFF”

Clear PSLOCI: AT+CRSM =214,28531,0,0,14,“FFFFFFFFFFFFFFFFFFFFFFFFFFFF”

Clear PSLOCI: AT+CRSM=214,28643,0,0,18,“FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF”

Thank you for the feedback. All of the QNVFD commands appear to run correctly, but I am getting errors with the CRSM commands. Here is my serial data.

Do you have any sugguestions?

Hi,

Are you insert SIM or without SIM to send those commands? BTW, which fw version are you using now? (AT+QGMR)
