Bladerf has established a connection with PC. after enabling srsenb, enter view trace to output the following contents, but it is unable to find signals through mobile devices The operation log is as follows:

The eNodeB was unable to establish an S1 connection with the EPC ("S1 Setup Failure. Cause: misc - unknown-PLMN").

Thanosss commented 4 years ago

Hello, what is the cause of this problem?(Sending S1 Setup Failure - Unknown PLMN)

alvasMan commented 4 years ago

Can you double check if the MCC and the MNC match on the eNB and the EPC?

kschepps commented 10 months ago

I'm also seeing Sending S1 Setup Failure - Unknown PLMN. I have wiped this PC numerous times and followed various tutorials, but this is as far as I'm able to get.

Edit: Sorry about the formatting. I can't figure out how to get the code boxes to show properly

Packet capture configuration

#

MAC-layer packets are captured to a file in the compact format which can

be decoded by Wireshark. For decoding, use the UDP dissector and the UDP

heuristic dissection. Edit the preferences (Edit > Preferences >

Protocols > DLT_USER) for DLT_USER to add an entry for DLT=149 with

Protocol=udp. Further, enable the heuristic dissection in UDP under:

Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp

For more information see: https://wiki.wireshark.org/MAC-LTE

Configuring this Wireshark preferences is needed for decoding the MAC PCAP

files as well as for the live network capture option.

#

Please note that this setting will by default only capture MAC

frames on dedicated channels, and not SIB. You have to build with

WRITE_SIB_PCAP enabled in srsenb/src/stack/mac/mac.cc if you want

SIB to be part of the MAC pcap file.

#

S1AP Packets are captured to a file in the compact format which can

be decoded by the Wireshark s1ap dissector with DLT 150.

To use the dissector, edit the preferences for DLT_USER to

add an entry with DLT=150, Payload Protocol=s1ap.

#

mac_enable: Enable MAC layer packet captures (true/false)

mac_filename: File path to use for packet captures

s1ap_enable: Enable or disable the PCAP.

s1ap_filename: File name where to save the PCAP.

#

configured.

srsran / srsRAN_4G

No signal found with bladerf #403

srsENB configuration file

eNB configuration

enb_id: 20-bit eNB identifier.

mcc: Mobile Country Code

mnc: Mobile Network Code

mme_addr: IP address of MME for S1 connnection

gtp_bind_addr: Local IP address to bind for GTP connection

gtp_advertise_addr: IP address of eNB to advertise for DL GTP-U Traffic

s1c_bind_addr: Local IP address to bind for S1AP connection

s1c_bind_port: Source port for S1AP connection (0 means any)

n_prb: Number of Physical Resource Blocks (6,15,25,50,75,100)

tm: Transmission mode 1-4 (TM1 default)

nof_ports: Number of Tx ports (1 port default, set to 2 for TM2/3/4)

mme_addr = 127.0.1.100

tm = 4

nof_ports = 2

eNB configuration files

sib_config: SIB1, SIB2 and SIB3 configuration file

note: When enabling MBMS, use the sib.conf.mbsfn configuration file which includes SIB13

rr_config: Radio Resources configuration file

rb_config: SRB/DRB configuration file

RF configuration

dl_earfcn: EARFCN code for DL (only valid if a single cell is configured in rr.conf)

tx_gain: Transmit gain (dB).

rx_gain: Optional receive gain (dB). If disabled, AGC if enabled

Optional parameters:

dl_freq: Override DL frequency corresponding to dl_earfcn

ul_freq: Override UL frequency corresponding to dl_earfcn (must be set if dl_freq is set)

device_name: Device driver family

Supported options: "auto" (uses first driver found), "UHD", "bladeRF", "soapy", "zmq" or "Sidekiq"

device_args: Arguments for the device driver. Options are "auto" or any string.

Default for UHD: "recv_frame_size=9232,send_frame_size=9232"

Default for bladeRF: ""

time_adv_nsamples: Transmission time advance (in number of samples) to compensate for RF delay

from antenna to timestamp insertion.

Default "auto". B210 USRP: 100 samples, bladeRF: 27

For best performance in 2x2 MIMO and >= 15 MHz use the following device_args settings:

USRP B210: num_recv_frames=64,num_send_frames=64

And for 75 PRBs, also append ",master_clock_rate=15.36e6" to the device args

For best performance when BW<5 MHz (25 PRB), use the following device_args settings:

USRP B210: send_frame_size=512,recv_frame_size=512

device_args = auto

time_adv_nsamples = auto

Example for ZMQ-based operation with TCP transport for I/Q samples

device_name = zmq

device_args = fail_on_disconnect=true,tx_port=tcp://*:2000,rx_port=tcp://localhost:2001,id=enb,base_srate=23.04e6

Packet capture configuration

MAC-layer packets are captured to a file in the compact format which can

be decoded by Wireshark. For decoding, use the UDP dissector and the UDP

heuristic dissection. Edit the preferences (Edit > Preferences >

Protocols > DLT_USER) for DLT_USER to add an entry for DLT=149 with

Protocol=udp. Further, enable the heuristic dissection in UDP under:

Analyze > Enabled Protocols > MAC-LTE > mac_lte_udp and MAC-NR > mac_nr_udp

For more information see: https://wiki.wireshark.org/MAC-LTE

Configuring this Wireshark preferences is needed for decoding the MAC PCAP

files as well as for the live network capture option.

Please note that this setting will by default only capture MAC

frames on dedicated channels, and not SIB. You have to build with

WRITE_SIB_PCAP enabled in srsenb/src/stack/mac/mac.cc if you want

SIB to be part of the MAC pcap file.

S1AP Packets are captured to a file in the compact format which can

be decoded by the Wireshark s1ap dissector with DLT 150.

To use the dissector, edit the preferences for DLT_USER to

add an entry with DLT=150, Payload Protocol=s1ap.

mac_enable: Enable MAC layer packet captures (true/false)

mac_filename: File path to use for packet captures

s1ap_enable: Enable or disable the PCAP.

s1ap_filename: File name where to save the PCAP.

mac_net_enable: Enable MAC layer packet captures sent over the network (true/false default: false)

bind_ip: Bind IP address for MAC network trace (default: "0.0.0.0")

bind_port: Bind port for MAC network trace (default: 5687)

client_ip: Client IP address for MAC network trace (default: "127.0.0.1")

client_port Client IP address for MAC network trace (default: 5847)

Log configuration

Log levels can be set for individual layers. "all_level" sets log

level for all layers unless otherwise configured.

Format: e.g. phy_level = info

In the same way, packet hex dumps can be limited for each level.
