YateBTS / bladeRF calibration

« on: February 07, 2015, 02:10:00 PM »

Hello,
published bladeRF for calibration isn't good for dummies at all.
What's the best way to calibrate bladerf in order to use YateBTS ?
like:
1. bladeRF-cli -i
2. set rxvga2 27
3. set rxvga1 25
4. set txvga2 -14
5. set txvga1 0
4. cal table dc rx 1841.6M 1842M 1000
5. cal table dc tx 1841.6M 1842M 1000

like this?
or it should be standard cal table dc tx/rx without freq ?

YateBTS / bladeRF rssi issues

« on: December 30, 2014, 11:18:27 PM »

Hello,
can anyone please help with few questions:
1. network not always appear in list on phone
2. even if its appear registration can take few minutes (tested on different models)
3. why RSSI level on phone never change, it always shows same value after it registered, lets say -48 db even when i'm 30 meters away

I guess transceiver settings should be adjusted like:
MinimumRxRSSI=-63
Radio.PowerManager.MaxAttenDB=5
and something else but I have no idea about those values....

 
bladeRF firmware & FPGA used from ./mbts/TransceiverRAD1




Please, guys, any suggestions.
