71 | 36 | roh | LimeNet Micro is a small all-in-one board combining the sdr, a gpsdo and some rf filters with a raspberry pi compute module3. |
72 | Due to the integrated gpsdo it should have no problems running tdma networks like gsm. |
||
73 | |||
74 | setup: install default raspbian (see getting started link below) and osmocom latest or nightly feeds. |
||
75 | config: use LNAL or LNAH for rx-path, BAND1 for tx |
||
76 | |||
77 | h2. RF Output Power |
||
78 | |||
79 | * +7dB in gsm900 (arfcn 5) |
||
80 | * -5dB in dcs1800 (arfcn 871) |
||
81 | |||
82 | in dcs1800 a reduction in rx power improves phase noise (e.g. max_power_red 5) |
||
83 | |||
84 | h2. Clock |
||
85 | |||
86 | do not select a specific clock on LimeNet Micro. (remove clock-ref line) |
||
87 | when this type of hardware is detected osmo-trx defaults to the gps synchronized clock from the fpga (gpsdo). |
||

102 | 19 | pespin | h1. OsmoTRX on LimeSDR |
103 | 1 | laforge | |
104 | 32 | pespin | In terms of OsmoTRX for LimeSDR, we now have @osmo-trx-lms@ which avoids the previously complex driver stack with UHD, SoapyUHD, SoapySDR, etc. All you need in terms of specific dependencies is: |
105 | * "LimeSuite":https://github.com/myriadrf/LimeSuite.git containing the actual drivers and utilities for LimeSDR (*version 17.09 or later required*, last release @18.06.0@ or @master@ really advised) |
||
106 | ** for LimeSDR-mini, you will need 17.10 or later (last release @18.06.0@ or @master@ really advised) |
||
107 | 1 | laforge | |
108 | 32 | pespin | If your distro doesn't ship with a LimeSuite new enough, it is advised that you install LimeSuite from osmocom repositories, see [[cellular-infrastructure:MacroBinaryPackages]]. |

118 | |||
119 | h3. Verifying the driver stack |
||
120 | |||
121 | You can ensure that LimeSuite recognizes your device using the *LimeUtil* part of LimeSuite: |
||
122 | |||
123 | <pre> |
||
124 | 18 | pespin | $ LimeUtil --find |
125 | * [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009060B00xxyyzz] |
||
126 | </pre> |

128 | 31 | pespin | h3. Running osmo-trx-lms with LimeSDR |
129 | |||
130 | 33 | pespin | If @rt-prio@ is set in .cfg file, running as root may be required. |
131 | 31 | pespin | |
132 | A sample cfg file to run @osmo-trx-lms@ with a LimeSDR device can be found in @osmo-trx.git@ in @doc/examples/osmo-trx-lms/osmo-trx-limesdr.cfg@. |
||
133 | |||
134 | <pre> |
||
135 | osmo-trx-lms -C osmo-trx.git/doc/examples/osmo-trx-lms/osmo-trx-limesdr.cfg |
