Maximu IPSP Channels in latest nRF SDK (14.2)

[Rafa]

Hi,
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 channels?.since my application needs more than one channel in case of initiator role.

Hi,

Yes, it is possible to increase the number of channels by increasing BLE_IPSP_MAX_CHANNELS, but increasing the channels means the Softdevice now needs that many times more memory. So you probably need to set aside more memory for it to work. We set aside a handsome 4k just for IPSP communication, so two channels means 8k reserved.
