 I am trying to run an application that needs to use ESB and BLE. For that I am using the ble_app_template (SDK 6.1.0) in which I have a included the esb_sd_resources_arm.lib (I am using Keil 4.73.0.0).
The first time I compiled it I got the errors</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 15 Jan 2015 02:59:50 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/5049/use-of-esb-with-s110" /><item><title>RE: Use of ESB with S110</title><link>https://devzone.nordicsemi.com/thread/17778?ContentTypeID=1</link><pubDate>Thu, 15 Jan 2015 02:59:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:17917105-aa2c-4309-807c-778ef79660b2</guid><dc:creator>Luis Alberto</dc:creator><description>&lt;p&gt;&amp;quot; There are 4 callback functions that are hard-coded with the ESB library, which needs to be declared in your project. If you look at the ESB example projects located in the SDK (esb_ptx_prx), you can see how they&amp;#39;re implemented. &amp;quot;&lt;/p&gt;
&lt;p&gt;-- Håkon Alseth&lt;/p&gt;
&lt;p&gt;The callback functions needed to be added in the code are:&lt;/p&gt;
&lt;p&gt;void nrf_esb_tx_failed(uint32_t tx_pipe)
{
}&lt;/p&gt;
&lt;p&gt;void nrf_esb_rx_data_ready(uint32_t rx_pipe, int32_t rssi)
{
}&lt;/p&gt;
&lt;p&gt;void nrf_esb_tx_success(uint32_t tx_pipe, int32_t rssi)
{
}&lt;/p&gt;
&lt;p&gt;void nrf_esb_disabled(void)
{
}&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
