This partially reverts commit 40d9dd4f1c5dcd0d4a2a1f0efcd225c9c4b36d6f, which does not only remove global variables from btcoex, as described on its commit message, but also does a few other things -- in particular, setting the default antenna position to BTC_ANTENNA_AT_MAIN_PORT. This drastically affects the upload performance and signal strenght on the HP 240 G4 laptop, as shown by the results bellow: Without this change: $ sudo iw dev wlp2s0 scan | grep -B3 JJ | grep signal signal: -42.00 dBm $ iperf3 -c 192.168.1.254 Connecting to host 192.168.1.254, port 5201 [ 4] local 192.168.1.253 port 39678 connected to 192.168.1.254 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 735 KBytes 6.02 Mbits/sec 1 1.41 KBytes [ 4] 1.00-2.00 sec 274 KBytes 2.25 Mbits/sec 1 1.41 KBytes [ 4] 2.00-3.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 4] 3.00-4.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 4] 4.00-5.00 sec 0.00 Bytes 0.00 bits/sec 1 28.3 KBytes [ 4] 5.00-6.00 sec 423 KBytes 3.47 Mbits/sec 3 41.0 KBytes [ 4] 6.00-7.00 sec 840 KBytes 6.88 Mbits/sec 0 58.0 KBytes [ 4] 7.00-8.00 sec 830 KBytes 6.79 Mbits/sec 1 1.41 KBytes [ 4] 8.00-9.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 4] 9.00-10.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 3.03 MBytes 2.54 Mbits/sec 7 sender [ 4] 0.00-10.00 sec 2.88 MBytes 2.41 Mbits/sec receiver iperf Done.
