https://devzone.nordicsemi.com/f/nordic-q-a/43765/does-any-nrf51822-based-modules-come-with-ota-ready-bootloaderI&#39;m planning to buy a nRF51822 based module for my BLE project &amp; I wanted to know whether any of the nRF51822 based modules come with OTA ready bootloader out of the box. This gets rid of purchasing a development kit for me as my budget is low.en-USTelligent Community 13Fri, 15 Feb 2019 14:30:38 GMThttps://devzone.nordicsemi.com/thread/171424?ContentTypeID=1Fri, 15 Feb 2019 14:30:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc3a4252-f7d2-4282-8c5e-3dbdf7a64ca9AndreasF<p>Hi.</p> <p>We do not sell any modules, only chips and development kits. There is unfortunately no way of knowing for what firmware 3rd party modules have flashed, you have to contact <a href="https://www.nordicsemi.com/Software-and-Tools/3rd-Party/3rd-party-modules">the supplies of 3rd party modules</a> and ask them.</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
