Alexander Chemeris alexander.chemeris at gmail.comHi all, Here is a patch which selects the latest nanoBTS firmware when it tries to connect to OpenBSC. This fixed the problem with NACKs for us. Sometimes (like in our case) nanoBTS has two firmwares and could boot any of them. Which one to boot is selected by a BSC during the initial OML setup. Originally OpenBSC selected the first firmware available, which gave us random results - sometimes the older firmware was booted, sometimes the newer firmware was loaded. With this patch OpenBSC always selects the latest firmware to boot (using simple string comparison of firmware version strings). In our case this now gives stable results. PS I don't have time to improve this patch if it's too hackish to be checked in, but I hope it will inspire someone to create a better one.
