 +==== Send a public broadcast message ==== 
 +Messages sent to the Public channel can be seen by anyone on the MeshCore network. They are repeated across the mesh by all repeaters that hear them. Other mesh nodes in range of you or a repeater that rebroadcast the message, should receive it. 
 + 
 +The public channel can be used as a large group chat for general conversation amongst all users on the mesh. It could also be used to send emergency alerts. 
 + 
 +It’s not recommended to send confidential information on the public channel as anyone can read these messages. 
 + 
 +To send a message: 
 +  * Tap the channels tab at the bottom of the screen. 
 +  * Tap the "Public" channel. 
 +  * Type a message and press the send icon.

 +==== Share your Contact Details (via QR Code) ==== 
 +Before you can send private, encrypted, direct messages to someone, you and the person you send the message to must both add each other as contacts. If the other person doesn’t also add you as a contact, your messages to them will fail to deliver. 
 + 
 +Contacts can be added in multiple ways: 
 +  * Privately in person by scanning QR Codes. 
 +  * Publicly via the mesh by sending and receiving an "Advert". 
 + 
 +To share your contact details privately via QR Code: 
 +  * Tap the 3 dot menu in the top right. 
 +  * Tap the "My Contact Code" menu item.

 + 
 +==== Share your Contact Details (via Advert) ==== 
 +If you are unable to privately share your contact details in person via a QR Code, you may alternatively share them publicly to everyone on the mesh by sending an "Advert". 
 + 
 +An advert is an unencrypted packet transmitted by your MeshCore node. It includes your node name, node type, public identity key and a cryptographic signature to prevent anyone from tampering with the information as it’s sent across the mesh. 
 + 
 +You can send two types of adverts: 
 +^  Zero Hop  ^  Flood Routed  | 
 +|The advert won’t be retransmitted by any repeaters. |The advert will be rebroadcast by all repeaters that hear it. | 
 +|Your contact details will only be received by nearby nodes. |Your contact details could be received by everyone on the mesh.| 
 + 
 +To share your contact details publicly via the mesh: 
 +  * Tap the signal icon in the top right. 
 +  * Tap the "Advert (Zero Hop)" or "Advert (Flood Routed)" menu item. 
 +  * Your contact details will be transmitted to the mesh.

 + 
 +==== Send Private Messages ==== 
 +Once you’ve added a contact, and that contact has added you back, you can send private messages to each other across the mesh. These messages are encrypted and only the intended recipient can read the message contents. 
 + 
 +To send a private message: 
 +  * Tap the contact you want to send a message to. 
 +  * Type a message and press the send icon. 
 +  * The app will try several times to deliver your message to the recipient. 
 +  * If it’s successful, it will show "Delivered" with a check mark. 
 +  * If an automatic acknowledgement from the recipient is not received after some time, the message will turn red and show as "Failed". 
 +  * When messages are received, they will show up in the conversation viewer. 
 + 
 +<WRAP group>

 +<WRAP center round info 70%> 
 +A message may get marked as failed even though it was successfully delivered to the recipient. This happens if we did not receive the acknowledgement reply from the recipient node. In this case, it’s recommended to send the message again. Once you see the delivered check mark, you know for sure it was received. 
 +</WRAP> 
 + 
 +<pagebreak> 
 + 
 +==== Retry sending a failed Direct Message ==== 
 +When you send a direct message to someone, it’s possible that it may not go through after several automatic attempts. This can happen for many different reasons, such as: 
 +  * Being out of range of the intended recipient. 
 +  * There are no repeaters in between you and the intended recipient. 
 +  * The intended recipient’s radio might be turned off. 
 +  * There might be interference on the radio spectrum. 
 + 
 +To try sending the failed message again: 
 +  * Long press the failed message shown in red. 
 +  * Tap the "Retry Sending" button shown in the message actions popup. 
 +  * Your message will try sending again. 
 +

 +</WRAP> 
 + 
 +<WRAP center round important 70%> 
 +When sending direct messages, **you must both add each other as contacts** first. The recipient's companion radio must be turned on to receive the message and to provide a delivery report. You must also be in radio range of each other, or have a working path of repeaters between each other. 
 +</WRAP> 
 +

 + 
 +==== Ping a Repeater ==== 
 +To check the signal strength to and from a nearby repeater, you can run a ping test. 
 +  * Tap the 3 dot menu icon next to a repeater contact. 
 +  * Tap the "Ping (Zero Hop)" menu item. 
 +  * A green popup will show signal strengths if successful. 
 +  * A red popup will show "Timeout" if your companion didn’t hear the repeater.

 +Ping tests do not hop through multiple repeaters. You must be in range of the specific repeater you are ping testing. For a ping test to be successful, the repeater must hear your companion signal directly, and your companion must hear the repeater signal directly. If you’re not in range of the repeater, the ping test will fail with a timeout error.

 +  * Double click on the reset button.
 +  * Open the drive that just mounted on your computer
 +  * Copy the ''.uf2'' file to the drive.
 +  * The drive may close on its own right away.  This is normal.
 +

 +  * Go to https://meshcore.io/flasher
 +  * Select your device
 +  * Select ''Repeater'' (or ''Room Server'')
 +  * Select ''Enter DFU Mode''

 +<pagebreak>
 +
 +Re-upload your settings:
 +  * Select ''Configure via USB'' from the previous page, or navigate to https://config.meshcore.io/
 +  * Select ''Connect''
 +  * Select ''Import''
 +  * Select your ''.json'' file
 +  * Scroll down to the ''Access'' section and retype your ''New Admin password'' (it doesn't remember it)
 +  * Scroll down and select ''Save settings''
 +  * Select ''Disconnect''
 +
 +Setup the Over the Air (OTA) update app (first time only):
 +  * Download the "nRF Device Firmware Update" app by "Nordic Semiconductor ASA" ([[https://play.google.com/store/apps/details?id=no.nordicsemi.android.dfu |Android]], [[https://apps.apple.com/sa/app/nrf-device-firmware-update/id1624454660 |Apple]])
 +  * Open the ''DFU'' app
 +  * In the settings, check ''Packet receipt notification''
 +
 +Perform an OTA update:
 +  * Using your phone's browser, navigate to https://meshcore.io/flasher
 +    * Select your device
 +    * Select ''Repeater'' (or ''Room Server'')
 +    * Select ''Download''
 +    * Select the firmware ''zip'' file (**not** the bootloader file)
 +  * Using the Meshcore app, login to your repeater (or room server) using the admin password.
 +    * For Room Servers: go to ''Remote Management''
 +    * Go to the ''Command Line''
 +    * Type ''start ota'', you should get a message that says: ''OK - mac: xx:xx:xx:xx:xx:xx''
 +  * Open the ''DFU'' app
 +    * Under ''File'' click ''Select'' to chose the firmware ''.zip'' file
 +    * Under ''Device'' click ''Select'' and chose the device that has ''DFU'' in the name.  If there are no device with ''DFU'' in the name select the device with ''OTA'' in the name.
 +    * Under ''Progress'' click ''Start''
 +    * If you selected a device with ''OTA'', the process will fail at ''DFU initialization''.  Not to worry, go back to the previous step and now you should be able to select a device with ''DFU'' in the name.
