I do see some unexpected values for the BER in response to the AT+CSQ command.
I am using an FX30 with a firmware based on the R14 release.
See here some traces captured from my system:
root@FX30:~# modem /dev/ttyAT 230400 AT+CSQ +CSQ: 24,86 OK
The AT command reference document 4118047_WPx5xx-76xx-77xx AT Command Reference_r6.pdf sates in the table 3-2 page 48 that the “ber” is either an integer, RXQUAL, or 99.
So I guess it is an integer equal to 86 in my case. How should I interpret it?
Is 86 a good or bad quality?
