I have the document for the proprietary commands but I can’t find the standard AT command reference. I have been provided with a modem to integrate into an existing product (upgrade from another brand of modem) so I don’t have the SDK. Where can I download the standard AT command reference please?
Thanks mlw but that it the proprietary commands document that I already have.
I am looking for all the standard commands such as AT+CREG and AT+CSQ.
Hi @lesgrant
Standard 3GPP AT commands support is listed in section 15 of the AT command guide: Supported GSM/WCDMA AT Commands
For detailed description of those commands you need to refer to the various public standard mentioned at the beginning of section 15:
- ITU recommendation v.250
- 3GPP TS 27.005 and TS 27.007
Thanks bbo. I was hoping that Sierra Wireless would have a document that covered all the AT commands as supported by a particular family of modems. Anyway, I have located and downloaded the following documents. I hope they are the correct (latest) versions…
