Hi guys, We were supplying Insys GSM Small 2.0 as part of our product, but it is extinct so I’m looking for a replacement. I have a FX30S, but it’s not accepting my ATD command. Here’s my setup and dial attempts: AT OK ATZ OK ATH OK AT+CSQ +CSQ: 12,0 OK AT+CGDCONT=1,“IP”,“[myapn.com](http://myapn.com)” OK ATD_99__1# ERROR ATD#GPRS ERROR ATD99__1# ERROR ATD99\*1 ERROR ATD_99 ERROR I’ve looked in the manual, but it’s not telling me much, nor are searches on these forums and elsewhere. What am I missing? Thanks for your help, Cheers, ScottCr ---

Hi jyiyji, thanks for the look-in. `ATD*99***1#` is my default dial string, it also returns error. ``` at!gstatus? !GSTATUS: Current Time: 241 Temperature: 22 Modem Mitigate Level: 0 ModemProc Mitigate Level: 0 Reset Counter: 1 Mode: ONLINE System mode: LTE PS state: Not attached LTE band: No band LTE bw: 1.4 MHz LTE Rx chan: 0 LTE Tx chan: 4294967295 LTE CA state: INACTIVE EMM state: Deregistered Attach Needed RRC state: RRC Releasing IMS reg state: No Srv PCC RxM RSSI: 0 RSRP (dBm): 0 PCC RxD RSSI: 0 RSRP (dBm): 0 Tx Power: 0 TAC: FFFF (65535) RSRQ (dB): 0 Cell ID: FFFFFFFF (4294967295) SINR (dB): 0 ``` Interesting that gstatus look all negative. I believe the SIMs are not enabled for 4G yet, but the modem then should drop back to 2G by default (3G is also blocked because the customer was having reliability issues). ---

USB is not an option. We need this modem to connect to an RTU, which does not have a USB port. I need a drop-in replacement for the Insys GSM Small 2.0. If a £200 modem fails, I need to replace it with another £200 modem, not rebuild the entire £5000 panel to get a modem working. ``` ati Manufacturer: Sierra Wireless, Incorporated Model: FX30S(WP7702) Revision: SWI9X06Y_02.16.06.00 7605a6 jenkins 2018/06/20 17:56:12 IMEI: 354723090118331 IMEI SV: 2 FSN: VU911670061310 +GCAP: +CGSM ``` ---

I think you downloaded the wrong FW. Didn’t you should download the fw from here which is for FX30S(WP7702)?

Hi [jyijyi](https://forum.sierrawireless.com/u/jyijyi), either I’m having a very blonde moment, or your documentation is seriously lacking. I’ve just spent an hour reading and Googling, but I cannot find a solid way to upgrade the firmware. The manual just says: ``` SSH on USB: 1. Copy FX30_WP8548_full_R14.0.4.002.cwe to the FX30 file system using scp. 2. Open an SSH session. 3. Execute fwupdate download FX30_WP8548_full_R14.0.4.002.cwe . ``` With some intuition I found the modem is at 192.168.2.2 when connected via USB, but what is the SCP username and password??
