YateBTS 2024

Everything to build and run the latest Yate + YateBTS + bladeRF xA4 for an old GSM 2G base station.

Yate 6.4.1 and YateBTS 6.1.1 use the latest bladeRF firmware and FPGA (tested with 2.4.0 and 0.15.3).

Bias Tee Support

The YateBTS now supports bias tee for both TX (bladeRF BT-100) and RX (bladeRF BT-200). To enable this feature, update the following settings in /usr/local/etc/yate/ybladerf.conf:

tx_bias_tee=: Set to yes to enable TX bias tee.
rx_bias_tee=: Set to yes to enable RX bias tee.

For more detailed tuning and configuration guidance, refer to the following documentation:

Tested (recommended) Build Environment

Raspberry Pi 5
bladeRF 2.0 micro xA4
Raspberry Pi OS Bookworm (64-bit Lite) (based on Debian 12 Bookworm), GCC-11/GCC-12, Apache2, PHP 8.2 (backwards compatible with PHP 5.6)

⚠️ WARNING: At least for Raspberry Pi 5 I do not recommend desktop image! Lite only as on desktop image IQ samples become negative in short time!

Installation Instructions

Clone the repository and run install.sh as a user; you will be prompted for your sudo password at some point. Compilation takes approximately 10-15 minutes on a Raspberry Pi 5. The script will install all dependencies, compile sources, and install Apache2 + PHP (if you choose the NiPC web interface).

Post-Installation Information

YateBTS Configuration:
- The base configuration is set for the 1900 MHz band, with MCC=310 and MNC=260.
- IMSI regex starts with 310260.
To start the Yate service:
```
sudo yate -s
```
To connect to YateBTS via telnet:
```
telnet localhost 5038

Example Usage of pySim

Here is an example usage of pySim (this can be used to program your first SIM):

./pySim-prog.py -p 0 -n YateBTS -c 1 -x 310 -y 260 -i 310260000000551 -s 8912600000000005512 -o 659BDA03311ACBBE767CB56D565A58D6 -k BA351F5C4690491D86377319E5A6DBCC
