Banana Pi BPI-R4 4G/5G Module sim card missing in modem manager

Hello, Does anyone here had similar issue liked this?

I installed a 4G/5G modem on BPI-R4 in M.2 Key-B slot, but i got an issue the modem couldnt detect sim card in modemmanager. I tried with three different type of 4G/5G modem still no luck. Changing different firmware also didnt work.

5G/4G Modem:

  1. Quectel RM520NGLAP-M20-SGASA(PCIe-Only)
  2. DW5821e Snapdragon X20 LTE(USB)
  3. Fibocom’s L850-GL(USB)

Damn, just as I was about to order the board.

Which sim slot have you tried (all three)? SIM1 (cn17) should be the right one. I have not tested sim slots on r4 yet

Yes, I’ve tested all three sim slots with three different sim provider still no luck.

Possibly defective board.

Could be hw issue (may affect more boards) this slot is not well tested yet by us externals…@dangowrt,have you a pcie key-b modem to test the sim-slot?

Its not a good news if it a defective board :sweat_smile:. I just received the board 3/4 days ago after waiting almost 1 month :melting_face: .

you can look which pins your modem uses from the ngff slot and compare with bpi-r4 schematics…maybe there is a difference

see pins 30-36 (even pins)

According to the Modem hardware design document the pin looks same. But i don’t know if there any differences cause i don’t know about electrical thing. :sweat_smile: :sweat_smile:

Here the link for hardware design document(Page39).

100% board is defective, check this image of FM350-GL.

Fibocom FM350GL works with with BPI-R4? What kind of configuration you run on BPI-R4?

That’s an image from Openwrt forum…

To me it seems that most modems expect the SIM-detection signal to be inverted. For the FM350-GL there is a AT command which allows you to ignore the SIM-detection signal, then it works on the R4 as PCIe device.

I have t99w175 (or something like that, writing from memory). Cheap version from Aliexpress for 50-60 USD. It works correctly. Was able to have modemmanager with it and openwrt. Have also Fibocom 350, but this still wait - was not able to have modem manager with it, so for the time being it is postponed. Additional question, when you put sim card and modem is on, do you have additional led light? I think it is blue.

The only modems worth buying are Quectel 5G modems, all other brands or modems are garbage and a waste of money.

What is the difference between the RM520N-GL AA and AP models?

Ø For RM520NGLAA, default communication interface is USB, PCle is disabled but could be enabled by AT command.

Ø For RM520NGLAP, default communication interface is PCle, USB is disabled and cannot be used.

i agreed with you. Its has problem with SIM detection with on board SIM Slot. I order this M.2(NGFF) Key B Adapter with SIM Card for 3G/4G/5G Module expansion board and insert the sim in the the expansion board, the modem manager pickup the sim on the expansion board.

I have module FM350GL but i doesnt have time to test with BPIR4. Yesterday i tried the module in BPIR4 with modem manager, the module works in modem manager.

When i put the sim card and on the BPIR4 the blue led light only flash once with booting process after the booting process complete the led doesnt light up.

I’ve read about T99W175 too but i not sure which version should i buy. Because T99W175 had many version. I saw another forum this module cloud work with USB but required some MODS. On your setup do you run the module in PCIe or USB protocol?

Thank you for sharing the info. I knew that the RM520NGLAA will work in most board because it has the USB line. The reason i choose RM520NGLAP because i had this module laying around and just want to test if the BPIR4 compatible with the PCIe only Modem. It also will be cheaper alternative if the RM520NGLAP work in BPIR4.
