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.
