Hey Draym, we are running into the same problem with providing co-existence with the ATWINC1500 WiFi module. Did you find any solution to the problem?

Thank you and best regards,

Saad

Hi,

Unfortunately there is no built in option for this.
One workaround is to use radio notifications. You can also look into a similar feature in the S132. This allows you to toggle a GPIO when the radio is ramping up and preparing to transmit BLE packets. Your wifi chip can then detect this signal and take action based on that. Unfortunately though, this just works one way. There is no way for the nRF52 to receive an external signal from your WiFi chip and have our BLE stack keep quiet while the WiFI chip is talking. A second option is to configure our BLE stack to only use channels outside of the radio band that your Wifi chip is using. You can e.g. configure your wifi chip to use wifi channel 1 and let the nRF52 use BLE channels 11 to 36. Here is a relevant post: Channel map setting for Wifi Coexistence.
What they are talking about in that thread is to run two radio protocols, e.g. ZigBee and BLE, on the same SoC. With our nRF5 SoC series it is possible to run multiple protocols at the same time by assigning timeslots to each protocol and multiplex between. Unfortunately you can't run wifi on our SoCs so this solution won't work for you.
