RC7611 setup correctly, but error on dial

[jyijyi]

you might try the same AT command as here:

[WP76xx] No PCM signal

@jyijyi I have follow your step , but the result still failed. I have set at!avcfg ,at!avsetprofile and at!avpifacepref, but still can’t get PCM signal. If I select internal codec, the signal is correct, so I think the HW is working well. Do you have any suggestion? ati9 Manufacturer: Sierra Wireless, Incorporated Model: WP7608 Revision: SWI9X07Y_02.25.02.01 000000 jenkins 2019/01/30 08:13:05 IMEI: 352913090101286 IMEI SV: 6 FSN: XG805285120904 +GCAP: +CGSM OK at!avcfg? !AVCFG: 0…
