Does anyone have any idea if the RM530N-GL works with the R4? I know the RM520N-GL-AA does. Seems like the 530 should but didn’t want to buy it if it was going to give me trouble.

Currently none modem works on the key-b slot as we don’t have this slot itself working.
Are you sure? With the stock software, from the BPi getting started page, they said the 520n-gl definitely works(screenshots provided). Sounds like it works because it uses the USB interface and not the pcie.
SinoVoip/Bananapi stock firmware got working PCIe on that slot, but lacks the drivers (MHI) to work with PCIe connected modems. So yes, there only USB-connected modem can work.
In vanilla OpenWrt we can easily add MHI drivers, but we didn’t get the PCIe controller serving that slot working yet.
Yes , that’s how I understood it as well. Assuming the RM530N-GL is usb interface as well, can I count on it to work with the R4? Am going to buy either the 520 or the 530 based on that.
If unknown I may just buy both of them, then report back after I try them.
The RM520N-GL works great on the snapshot from openwrt, with the needed packages installed. making this post right now from it.

Package list please, thanks!
I can confirm that the Quectel RM521F-GL (engineering sample) from AliExpress also works on the stock firmware.

Other than the base packages, I added uqmi, kmod-usb-serial, kmod-usb-net-qmi-wwan, kmod-usb-serial-option, kmod-usb-serial-wwan, and picocom. I used picocom to figure out the apn settings. Using it right now to post. Also, verizon wouldn’t let that device on, using picocom I changed it’s imei to the imei of the tablet I had that I’m not using.

Thanks, I’m really want to learn all this.
Hi, did you eventually get the RM530N-GL to work? I’m considering building a router based on BPI-R4 and am choosing between RM520N-GL and RM530N-GL.
I am trying to do the same. I had spent the weekend trying to get mine online. I could see like 3 towers and connecting to band 13 but wouldn’t connect to internet. It said registering denied and the sim card is already registered and is a 5g tablet sim card on verizon. I had used socat on of the the firmwares on tried it already has the tablet sim. X-wrt had a bunch of packages installed and it was the opkg not apk. I tried the lastest snapshots to begin with only apk didn’t get very far. The one I got the furthest on was X-wrt eventually the webpage started loading and then couldn’t access it just couldn’t do anything. Is there a way you can send one for me to download and if need to change anything on mine that would be great to know. I tried many protocols modemmanager, qmi, mbim, qmat, and 3g-info lite. I dont think some of those even work anymore but were some great tools. If I can’t get any help I may just buy the cudy router on amazon. I also have a rn520n-gl glaa if there any more info you need I will try and give it.
Also on each firmware that I could even boot. I had all of those packages installed stated above. I even got to do AT commands.
I’ve tried using picocom to put in the APN settings now I’m getting an error that says invalid operation for uqmi commands. Tried rebooting not fixing it. I need some help please. I have also tried gfriend wrt still no luck.
To better assist you, could you confirm if the issue with the invalid operation for uqmi commands has been resolved? If not, we can explore further troubleshooting steps.
How do you want me to confirm it try to do it again? Currently I have the gfriend wrt firmware installed it shows the service towers and the band but I can’t get online what do I need to show you that it’s not working?
Which gfriendwrt firmware version have you tested? Have you try the latest version?
Do you have discord I can try everything you want right now?
