i just had the first phone call between iphone and mnt pocket reform. i could hear my voice, spoken into the iphone in good quality on the pocket, which i didn't expect. i was able to play back random audio files over the phone line to iphone, but they're so far mega distorted. kinda like if the bits are the wrong way around, or 8/16 bit mismatch. in any case, it was quite fascinating.

@mntmn With proper modding, pocket reform could really become another PC110.

for extra clarification: this was with quectel em06 modem inserted into pocket reform. the audio lines are connected to SAI3 of the imx8mplus.

@mntmn by far the biggest issue with the quectel audio on the pinephone was samplerate mismatches

@martijnbraam and @mntmn, let’s say I have the deranged desire to use my laptop for phone calls and SMS, what is the best option for a modem?

@cnx @martijnbraam phone calls don't just work with any laptop/device. it has to have a SAI/I2S/PCM... interface hooked up to the modem's digital audio lines. i've heard there are rare modems with usb audio but don't know which ones

Thanks for the explanation, @mntmn, I will keep dreaming then :ym_daydreaming:

serghov,

@mntmn @cnx @martijnbraam doesn't the modem in pinephone (pro) support audio routing through usb with open source firmware?

@serghov @mntmn @cnx pretty sure it's possible yes, I know that the modem in the librem 5 ran with usb audio for a while

Thanks, @martijnbraam and @serghov, what does that mean if I want to get it to work on my laptop? ELI5, suppose I connect to the Librem 5 modem, will I then read the SIM card and then use that data with the modem in what way? Cc: @mntmn

oldkid,

@mntmn hello minute, this reminds me, I once talked about China Unicom support with you, and it seems that em05 supports China Unicom. I found this on the local online store, does it look like something that can be plugged into the pocket reform?

@oldkid yes!
