https://devzone.nordicsemi.com/f/nordic-q-a/31264/maximu-ipsp-channels-in-latest-nrf-sdk-14-2Hi, Does BLE IPSP profile limits the maximum channels a one? I tried to change BLE_IPSP_MAX_CHANNELS to two, but it results code crashing at nrf_sdh_ble_enable() API. Is soft device is limiting the channels?. Is there any way to increase this channelsen-USTelligent Community 13Mon, 12 Mar 2018 13:09:42 GMThttps://devzone.nordicsemi.com/thread/123925?ContentTypeID=1Mon, 12 Mar 2018 13:09:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1bf611a-5573-4686-be82-93ec349080caMttrinh<p>Hi,</p> <p>Yes, it is possible to increase the number of channels by increasing&nbsp;BLE_IPSP_MAX_CHANNELS, but increasing the channels means the Softdevice now needs that many times more memory. So you&nbsp;probably need to set aside more memory for it to work.&nbsp;We set aside a handsome 4k just for IPSP communication, so two channels means 8k reserved.</p> <p>&nbsp;</p><div style="clear:both;"></div>
