To save power in a battery operated device, I want to be able to turn wifi on and off and planned to use BLE to do that. However, it appears that these are linked in AMB82-mini, so you can’t have BLE working alone. If wifi is turned off, then BLE is also off and vice versa. Is this the expected arrangement? Is there a native way to achieve what I need? Update: So wifi is off initially, and BLE is on at reboot. However, when wifi is turned on, it can’t be turned off without turning off BLE. Barry ---

Hi Barry, Understanding that power saving is your priority, we do have a low power bluetooth chip + AMB82-mini working solution, where user could control AMB82-mini such as switching WiFi on and off using a low power bluetooth chip. Please let us know if you are interested in this solution. Thank you. Best regards, Kevin ---

Hi Kevin, yes, this is what we have been trying to implement - we have been able to switch wifi on using BLE, but if we then switch it off (to save power), it seems that also switches off BLE - so we can’t then switch on wifi again (unless the board is reset). Is this the expected operation? Best regards, Barry ---

Hi Barry, This is expected as BLE and WLAN both share the same radio resources. However, this can be addressed by adding an additional low-power bluetooth chip. We strongly recommend you to use the low-power bluetooth chip + AMB82-mini solution to implement the BLE+WiFi operation. Thank you. Best regards, Kevin ---

Thanks Kevin, actually that was our initial plan, but thought it would be possible to use the onboard BLE. Thanks again for your support. Regards, Barry ---

Hi Pammy, I’m interested in the low-power bluetooth chip + AMB82-mini solution for a product we’re working on - I’ve looked at the GH repo, but haven’t been able to identify a schematic there. Are you able to share more information on this with me via email? Regards. Corin ---
