+In order to receive access to the Pymesh firmware releases (for Lopy4, Fipy, L01 or L04), please follow the steps from [Pybytes - Pymesh integration](/pybytes/pymeshintegration/).
## Test Pymesh firmware loading
### Method 1
-The simplest way to check if the Pymesh class has been successfully installed is to try the following code, directly in REPL:
+The simplest way to check if the Pymesh class has been successfully instantiated (and started inside Pybytes) is to try the following code, directly in REPL:
```python
->>> from network import LoRa
->>> lora = LoRa(mode=LoRa.LORA)
->>> mesh = lora.Mesh()
+# todo: add try/except for checking pybytes object exists
+>>> pymesh = pybytes.__pymesh.__pymesh
+>>> pymesh.cli_start()
+>h
+List of available commands
+br - enable/disable or display the current Border Router functionality
+brs - send packet for Mesh-external, to BR, if any
+buf - display buffer info
+config - print config file contents
+debug - set debug level
+gps - get/set location coordinates
+h - help, list of commands
+ip - display current IPv6 unicast addresses

+mml - display the Mesh Mac List (MAC of all nodes inside this Mesh), also inquires Leader
+mp - display the Mesh Pairs (Pairs of all nodes connections), also inquires Leader
+ot - sends command to openthread internal CLI
+pause - suspend Pymesh
+resume - resume Pymesh
+rm - verifies if any message was received
+rst - reset NOW, including NVM Pymesh IPv6
+s - send message
+self - display all info about current node
+sleep - deep-sleep
+stop - close this CLI
+tx_pow - set LoRa TX power in dBm (2-20)
+ws - verifies if message sent was acknowledged
